“Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52).”

If you are one of the users who encountered this kind of error on your Windows 10 computer, read on as this post will guide you on how you can fix this Bluetooth error. According to security experts, the key to fixing this error is to sign the Bluetooth A2DP files with the built-in tool, System File Checker. Apart from that, you could also run the Hardware and Devices troubleshooter or perform System Restore, as well as update or reinstall the concerned drivers.

  • Lastly, check if the Startup type is set to Manual.

Option 2 – Try running System File Checker or SFC scan

You could also run System File Checker or SFC scan to fix the Bluetooth error. It is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Reboot your PC.

Option 3 – Try to perform System Restore

You might also want to perform System Restore as the error might be caused by system modifications. Thus, to undo them, you can use System Restore. Run it using these steps:

  • First, tap the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
  • After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 4 – Try running the Hardware and Devices Troubleshooter

The next thing you can do to fix the problem is to run the Hardware and Devices troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the Bluetooth error. To use it, refer to these steps:

  • The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
  • After opening Settings, look for the Update and Security option and select it.
  • From there, go to the Troubleshoot option located on the left-hand side of the list.

  • After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 5 – Try to reinstall or update the Bluetooth driver

The issue might have something to do with the Bluetooth drivers. It could be that it is outdated and needs to be updated or that you recently updated it and since then you have trouble removing the Bluetooth devices and so to fix the issue, you can update, roll back or uninstall the Bluetooth drivers. How? Follow the steps below.

  • Tap the Win + X keys to open the Device Manager.
  • Next, look for the Bluetooth device and right-click on it.
  • Select the option “Update driver”.
  • After that, a new popup window will appear. In there, select the option, “Search automatically for updated driver software”.

Note: Checking the update may take a few minutes so you’ll have to wait until it finishes. If it is able to find an update, you must install it. And if you want to reinstall the Bluetooth driver, just select the “Uninstall driver” option and follow the next on-screen instructions that follow.

Taskbar is not visible in Remote Desktop
Recently, several users reported an issue on their Windows 10 computers where the taskbar is not visible when they tried to connect to a computer via Remote Desktop Protocol or RDP. The Remote Desktop Connection feature uses the RDP which allows users to access a computer remotely. This is actually different from the taskbar being hidden automatically until the pointer hovers on it since, in this scenario, the taskbar is completely not accessible which makes using the remote computer entirely difficult, if not impossible. There are several suggestions you can check out to resolve this problem, you can try to restart the process of Windows Explorer via Task Manager or you could clear the cache for multiple processes. You could also try to reinstall the Shell Experience components or show the local taskbar in the Remote desktop. Moreover, you could also try to update, uninstall or roll back the display driver/graphics card driver. For more details, refer to each one of the options given below.

Option 1 – Try to restart the Windows Explorer process

The first option you have to try to fix the problem with the taskbar is to simply restart the Windows Explorer process in the Task Manager.
  • Tap the Ctrl + Shift + Esc keys to open the Task Manager.
  • Next, go to the Processes tab and find the process of Windows Explorer.
  • Once you find it, right-click on it and select Restart to restart its process.
  • After that, restart your computer and see if you can now see the Taskbar.

Option 2 – Try clearing the cache of multiple processes

The next thing you can do to resolve the problem is to clear the cache of many processes in your computer. To do so, follow these steps:
  • Open the Notepad app and paste the following content in the text area:
@echo off taskkill /f /im explorer.exe taskkill /f /im shellexperiencehost.exe timeout /t 3 /NOBREAK > nul del %localappdata%PackagesMicrosoft.Windows.ShellExperienceHost_cw5n1h2txyewyTempState* /q timeout /t 2 /NOBREAK > nul start explorer @echo on
  • After that, tap the Ctrl + S keys to save the changes you’ve made in Notepad and select the “All files” as its file type, and then name it “CacheClearTWC.bat”.
  • Next, go to the location where you saved the file using File Explorer and then run it. This will run a couple of batch scripts which will clear the cache of multiple processes in the system.
  • Tap the Win + X keys and select the “Windows PowerShell (Admin)” option to open PowerShell as admin.
  • Next, execute this command in the command line: Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “appxmetadataappxbundlemanifest.xml”)}
  • After the command has been executed, this will reinstall the Shell Experience components and should fix the problem with the taskbar.

Option 4 – Update, uninstall or rollback the Graphics card drivers

  • First, boot your computer into Safe Mode.
  • After that, tap the Win + R keys to launch Run.
  • Type in MSC into the box and tap Enter or click OK to open the Device Manager.

Restore, Minimize and Close are not working
Recently, a number of users reported not being able to use the Restore, Minimize and Close buttons on their Windows 10 computers. This kind of issue can be quite annoying as you won’t be able to use your computer properly, especially when you navigate between programs and windows. In such cases, the buttons on the right side of the title bar won’t respond to any inputs which could be caused by a number of factors such as different input modes, corrupted system files, and many more. If you are one of the users who are currently facing this problem, worry not for this post will guide you on what you can do to resolve it. There are several potential fixes you can check out to fix the issue. You can try to check if Tablet Mode is enabled and if it is, you have to disable it. You could also boot your computer in a Clean Boot State to check if a third-party program is the one that’s causing the problem. In addition, you could also reinstall the program where you experience the problem or run built-in utilities like System File Checker and DISM tool.

Option 1 – Make sure that you are not in Tablet Mode

Since Windows 10 is designed to work on both desktop and mobile devices, it could be that your computer has slipped into Tablet Mode which explains why you’re not seeing the Taskbar. To check if your computer is really in Tablet Mode, follow these steps:
  • Go to the Start menu and select Settings.
  • Next, select the System setting and from the left pane select the Tablet Mode.
  • From there, make sure that the buttons next to the options given below are set to the off position:
    • Hide app icons on the taskbar in tablet mode
    • Automatically hide the taskbar in tablet mode

Option 2 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • Once your computer is in a Clean Boot State, try to open the program where the problem occurred.

Option 3 – Try reinstalling the program

If the first two options didn’t work, then you might want to consider uninstalling the program and then install it back with its latest version. This should resolve the problem.

Option 4 – Try to run System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why the Restore, Minimize and Close buttons don’t work. To run the SFC command, follow the steps given below.
  • Type “cmd” in the Start search and then right-click on the appropriate search result.
  • Next, select “Run as administrator” to open Command Prompt with admin privileges.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Now restart your computer and see if the problem is fixed or not.

Option 5 – Run the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the problem. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
  • Open the Command Prompt with admin privileges.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • exe /Online /Cleanup-image /Restorehealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish. Once it’s done, restart your computer.

Outlook 2013 Preview
Hello and welcome to our Outlook 2013 Preview. Everyone has heard of sneak peeks when it comes to new movies and games that are coming out soon. That is what advertisements and test reels are for to get the audience interested and excited before the piece of media even comes out. It serves to entertain the target audience in the months, maybe even years, up until the release date of this thing they want to play or see and it keeps it in the public mind. It is also great for the viewers because it is a hint to what they will expect when it comes out and it keeps them wanting more excitedly. However, did you know that sometimes computer software releases previews and sneak peeks too?

Outlook 2013

Well, they do and Microsoft has released some sneak peeks and previews of their new Outlook, Outlook 2013! This is probably to get consumers ready for when it comes out next year; people are going to be getting excited about this new makeover that Microsoft Office, with Outlook, has given itself, people from Microsoft even saying it is ‘the most ambitious’ version of Office yet! The new orange color scheme and logo design look promising enough for the consumer without even checking the new features and special things that have been revealed about it yet!

Outlook 2013 Features

The best part of this new Outlook is that you can move widgets around in it. If you don’t like the fact that your inbox is placed over your outbox, you can move it- simple as that! It will be really handy for people who like messing around with layouts and will also be handy for people who tend to overlook things at the bottom of the pile like spam and trash if they can move them to a more noticeable location for themselves. Another great thing is that the new Microsoft Office that Outlook comes with has a cool new stylus option, allowing you to personalize things with your own handwriting or even drawings. This can then be used as your email signature on Outlook which can give a really nice and personal feel to the emails you are sending. Another new thing is their labeling of drafts. Like Gmail, Google’s own email service, a red-lettered ‘draft’ will now appear over composing messages you have not yet sent.

Handy Email Tools in Outlook 2013

This is handy because you know where your message has been saved as opposed to how it could be saved in your outbox or be sent to the trash. Also, there are new links with Facebook that allow you to see what your friends are doing through Outlook. You can also converse with Facebook friends through Outlook now, which is a big step forward in this age of social media. You can get an email from a person and, at a click of a button, also read all their Facebook posts. However, there is not an option for Twitter or Tumblr or even Myspace, which is a shame I suppose, but maybe in the next update. So, I think Outlook 2013 will be worth looking at, don’t you?

How to Fix Windows 10 Error 0x8007007b

Error code 0x8007007b - What is it?

Error code 0x8007007b will present itself when Windows users are trying to activate Windows. You may try to activate it through the update and security option, but it is likely that you will receive the same error code. Error code 0x8007007b may be presented when Windows 7 and Windows 8.1 users try to upgrade and activate Windows 10 on their computer.

Common symptoms include:

  • An error message will display that says Windows cannot be activated. The KMS host cannot be located in the DNS, please have the system administrator verify that the KMS is published correctly in DNS.
  • Error 0x8007007b will be displayed, stating that the file or directory name or the volume label syntax is not correct.

Solution

Restoro box imageError Causes

There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

  • Click Start, type in regedit, and then press Enter.
  • Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
  • The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

  3. Change permissions for /usr/local/flexnetserver/ directory to 777
  • Open Terminal (located in /Applications/Utilities/Terminal) and enter the following command:
sudo chmod -R 777 /usr/local/flexnetserver
  • Note: Administrator password may be asked. While typing no characters are shown, just type out the password and hit return key.
  • Note: To start the license server only with elevated permissions (using sudo command), change permissions to 755 instead of 777.
  1. Create /usr/local/flexnetserver/licenses directory for network license file location
sudo mkdir /usr/local/flexnetserver/licenses
  1. Find the license server Host Name and Host ID.
  2. Generate the Network License File in the Autodesk Account
    • Once the license file is generated, make sure it has a .lic extension (e.g. adsk_license.lic) and is in a plain text format and place it in /usr/local/flexnetserver/licenses directory
Note: In this article we will refer to  adsk_license.lic as network license file name. Feel free to change the actual name of the license file, but make sure to reflect the new name when using the commands below.
  1. Create a debug.log file in the /usr/local/flexnetserver/ directory using the following command:
touch debug.log
  1. To start the Network License Server use the following command:
/usr/local/flexnetserver/lmgrd -c /usr/local/flexnetserver/licenses/adsk_license.lic -l /usr/local/flexnetserver/debug.log
Note: If folder permissions for  /usr/local/flexnetserver/ are set to  775, then use sudo command to start the server. For example:
sudo /usr/local/flexnetserver/lmgrd -c /usr/local/flexnetserver/licenses/adsk_license.lic -l /usr/local/flexnetserver/debug.log
  1. To obtain license server status enquiry:
/usr/local/flexnetserver/lmutil lmstat -a -c /usr/local/flexnetserver/licenses/adsk_license.lic
  1. To stop the license server:
/usr/local/flexnetserver/lmutil lmdown -q -force
  • A​​lternatively, run ps command to obtain process ids for lmgrd and adskflex and then kill those processes:
ps -ax | grep lmgrd
ps -ax | grep adskflex
kill -9
  • (provide process ids obtained by previous commands individually)

How to set up the Autodesk Network License Manager on Linux.

Note: The Autodesk License Manager (11.16.2.0) is supported only on the following Linux distros:
  • Red Hat® Enterprise Linux® 7
  • Red Hat Enterprise Linux 6
  • SUSE Linux Enterprise 12
  • SUSE Linux Enterprise 11
To configure the license manager use the following steps:
  1. Download Autodesk Network License Manager v. 11.16.2 for Linux from this link
    • ​​Download the nlm11.16.2.0_ipv4_ipv6_linux64.tar.gz file to your desktop.
  2. To install the Autodesk Network License Manager run following command as root.
    • tar –zxvf nlm11.16.2.0_ipv4_ipv6_linux64.tar.gz
    • rpm -vhi nlm11.16.2.0_ipv4_ipv6_linux64.rpm
    • The license server will be installed in /opt/flexnetserver/ directory.
  3. Find the license server Host Name and Host ID
  • To obtain the license server system hostid run the following command
/opt/flexnetserver/lmutil lmhostid From the command output note the hostid in quotes, if the system has two active NIC cards, select the first MAC address. lmutil - Copyright (c) 1989-2018 Flexera. All Rights Reserved. The FlexNet host ID of this machine is "000c297949e0"
  • To obtain the license server system hostname run the following command
/opt/flexnetserver/lmutil lmhostid hostname From the command output note the hostname of the license server. mutil - Copyright (c) 1989-2018 Flexera. All Rights Reserved. The FlexNet host ID of this machine is "HOSTNAME=Centos7.localdomain"
  1. Generate your Network License File in Autodesk Account
    • Once the license file is generated, make sure it has .lic extension (e.g. adsk_license.lic) and place it in /opt/flexnetserver/licenses directory.  If the directory doesn't exits, create it with this command: sudo mkdir /opt/flexnetserver/licenses
Note: in this article we will refer by adsk_license.lic your network license file name.
  1. To start the Network License Server
    • /opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/adsk_license.lic -l /opt/flexnetserver/server_log.log
  2. To obtain license server status enquiry
    • /opt/flexnetserver/lmutil lmstat -a -c /opt/flexnetserver/licenses/adsk_license.lic
  3. To stop your license server service
    • /opt/flexnetserver/lmutil lmdown -q -force
    • alternatively you can also run ps command to obtain process ids for lmgrd and adskflex and then kill those processes
      • ps -aw | grep lmgrd
      • ps -aw | grep adskflex
      • kill -9 (provide process ids obtained by previous commands individually)
  4. To start the license server automatically after the system reboot
    • Open /etc/rc.d/rc.local script as root and enter license server start up command in it.
touch /var/lock/subsys/local /opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/adsk_license.lic -l /opt/flexnetserver/server_log.logNote: To ensure that the script will be executed during boot, run following command as root. chmod +x /etc/rc.d/rc.local
  1. Make sure that all necessary ports are open:
  • lmgrd.exe needs ports 27000 to 27009.
  • adskflex.exe needs port 2080.
Note: Errors may occur if the network license file is corrupt or in the case of a combined network license it has incorrectly combined licenses. To learn more about combining licenses, see Combining License Files for Multiple Autodesk Products. Use the License File Parser to verify that the license contains the appropriate products and FLEXnet feature codes and does not display an error

Verify that TCP ports (2080, 27000-27009) used by Autodesk Network License Manager are not blocked by Firewall.

The FLEXlm® based version uses the following incoming ports:
  • TCP ports 2080 (for the adskflex vendor daemon)
  • TCP ports 27000 to 27009 (for the lmgrd master daemon, which uses the first open port in the range)
Note: If these port addresses are restricted by a router or firewall software, users on the remote side of the router will not have access to licenses controlled by the Network License Manager.

Verify that the client computer is configured with the correct license server name or IP.

Windows:

Clear license server information from the system registry.

  1. Type regedit in the Windows Search box and hit Enter key.
  2. Select the following registry key
  • [HKEY_CURRENT_USER\SOFTWARE\FLEXlm License Manager]
  1. As the key is selected, in right panel ADSKFLEX_LICENSE_FILE will be visible.
  2. Right click on the key and delete it.

Specify the license server in ADSKFLEX_LICENSE_FILE system variable 

  1. Go to Start > Control Panel > System and Security > System.
  2. Select Advanced system settings.
  3. On the System Properties dialog, click Environment Variables.
  4. Under System Variables, click New.
  5. Enter ADSKFLEX_LICENSE_FILE for the variable name and 2080@SERVER_NAME _OR _IP for the variable value.
Note: the license server information most often is recorded in LICPATH.lic file and can be verified there too.  ADSKFLEX_LICENSE_FILE system variable supersedes LICPATH.lic.  Thus, setting the system variable is preferable when this error is seen.

If the license server is on a VPN or a remote network set the FLEXLM_TIMEOUT environment variable:

  1. Go to Start > Control Panel > System and Security > System.
  2. Select Advanced system settings.
  3. On the System Properties dialog, click Environment Variables.
  4. Under System Variables, click New.
  5. Enter FLEXLM_TIMEOUT for the variable name and 5000000 for the variable value.
  6. Click OK to save the setting.
Note: if needed the variable value can be increased to 10000000.

Mac/Linux:

Specify the Autodesk Network License server information in $HOME/.flexlmrc file.

Use a text editor to create a flexlmrc.txt file and save it in Plain text format (In TextEdit on Mac: Format - Make Plain Text) on desktop. The file content should look like this, except with the name or IP address of the license server.
  • ADSKFLEX_LICENSE_FILE=@SERVER_NAME _OR _IP
If the license server is on the same machine as the Autodesk software, use localhost as the license server name.  Thus, the content of flexlmrc file could look like this:
  • ADSKFLEX_LICENSE_FILE=@localhost
Note: On firewall restricted network or when accessing the license server via VPN, need to include TCP port/s (usually 27000 or 2080) into Autodesk License Server service as follows: ADSKFLEX_LICENSE_FILE=2080@SERVER_NAME _OR _IP

Once flexlmrc file is created move it to user's $HOME folder as follows:

  1. Open a Terminal window
  2. Type open ~ (Mac) or nautilus ~ (Linux) to open $HOME folder
  3. Drag and drop flexlmrc.txt file from Desktop to the home folder.
  4. To make the file a configuration file, rename it to .flexlmrc (please note . [DOT] in front of the file name) by running the following command:
  • mv flexlmrc.txt .flexlmrc (Mac)
  • mv flexlmrc .flexlmrc (Linux)

Verify that the license server information registered with the product is correct (versions 2020 and later only)

In versions 2020 and later, the license server information is registered with the AdskLicensing service running locally on the workstation. When changing to a new license server, the old server information may still be registered with AdskLicensing and result in the error above, if this is not appropriately updated. See the below steps to solve this:
  1. Click the Start menu and type cmd.
  2. Right-click on the Command prompt and choose "Run As Administrator."
  3. In the Command prompt, run the following command, followed by ENTER:

"C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\helper\AdskLicensingInstHelper.exe" change -pk PRODKEY -pv VER.0.0.F -lm "" -ls "" -lt""

Note:

  • Replace PRODKEY with the product key correspondent to your product(s). See Look Up Product Keys for the full list.
  • Replace VER with the version you are using. E.g. 2020 for AutoCAD 2020.
  • Repeat this step for each software you need to reset.
  1. Open Registry Editor (Start > type regedit > ENTER).
  2. Navigate to HKEY_CURRENT_USER\Software\FLEXlm License Manager.
  3. On the right-side, verify of the ADSKFLEX_LICENSE_FILE key exists. If yes, remove it (right-click > Delete).
  4. Run the software again.
  5. Select Multi-user in the Let's Get Started screen.
  6. Follow the steps to connect to your license server.
