Next, in the Start search, type in PowerShell and right click on the result, and select the “Run as administrator” option.
After that, type the following commands to re-register the Windows 10 apps. Make sure to hit Enter on each line:
- reg delete "HKCUSoftwareMicrosoftWindows NTCurrentVersionTileDataModelMigrationTileStore" /va /f
- get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmetadataappxbundlemanifest.xml")}
- $bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname
- get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmanifest.xml")}

Option 4 – Try to run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help in fixing the problem.

Cannot save media from Microsoft Photos

The Microsoft Photos app is a useful tool that allows users to view, edit, as well as create videos on their Windows 10 computers. Although it works just fine most of the time, there are some instances when you might encounter some issues when using it. One of these issues is when you cannot save media from the Photos app after you’ve edited an image. This is most likely related to a permission issue. However, according to some users, they got the error where the edited media file can’t be saved. When you encounter this kind of error, you will see the following error in your Photos app:

“It looks like you don’t have permission to save changes to this file. Try saving a copy instead.”

There are several options you can explore to resolve this error. You can try updating the Microsoft Photos app or verify the ownership of the destination folder. You can also re-register and reinstall the app. For more detailed instructions, make use of the options provided below.

Option 1 – Try to update the Microsoft Photos app

The first thing you can do to fix the problem is to update the Microsoft Photos app.

Open the Microsoft Store and click on the three horizontal dots for the menu located on the top right portion of the window to see the options.
Next, select Downloads and updates and then click the Get updates button in the top right. This will install any pending updates for all the apps including the Microsoft Photos app using the Microsoft Store.

Option 2 – Try to verify the ownership of the destination folder

The next thing you can do to fix the error is to verify the ownership of the folder because chances are, the location where you’re trying to save the file might not have enough permissions to read and write the file to the disk. Thus, you need to take ownership of the folder by following these steps:

Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
Next, type and enter this command: TAKEOWN /F <path>
Note that the <path> is the location of the folder or file in File Explorer.
Now type and enter this second command: ICACLS <path> /grant administrators:F
Finally, once the command has been executed, restart your computer and then see if you can now access the folder or file.

Option 3 – Try resetting the Photos app

If the first option of restarting the background process of the Photos app didn’t work for you, you can try to reset the Photos app so that it will use the default factory settings. Note that this option works when you are experiencing this issue after making a couple of changes in the Photos app.

To get started in resetting the Photos app, open the Windows 10 Settings.
Then go to Apps > Apps & features.
After that, scroll down until you see the Photos app option – click on it and open its Advanced options.
From there, you will see the Reset button, click on it and click and then click on it once more to confirm.

Note: The process may take a couple of minutes to complete. Once it’s done, open the pictures again using the Photos app.

Option 4 – Try reinstalling the Photos app

If none of the first two options given above worked, then you might want to consider reinstalling the Photos app. Unlike what most users think, it isn’t really that hard reinstalling preinstalled apps as you have the Windows PowerShell for that. To use this program in reinstalling the Photos app, follow these steps:

Open the Windows PowerShell program with admin privileges and key in the following command:

Set-ExecutionPolicy Unrestricted

After that, execute this second command to re-register and reinstall the Microsoft Photos app.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Note: In the command given, do not forget to replace the “PackageFullName” with the actual package name for the Photos app. After executing the command, it will uninstall the Photos app from your computer so you need to install it again from the Windows Store by simply looking for it. Once you found it, just click on install to start the installation process.

/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"

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.

To start the Network License Server
- /opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/adsk_license.lic -l /opt/flexnetserver/server_log.log
To obtain license server status enquiry
- /opt/flexnetserver/lmutil lmstat -a -c /opt/flexnetserver/licenses/adsk_license.lic
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)
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

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.

Type regedit in the Windows Search box and hit Enter key.
Select the following registry key

[HKEY_CURRENT_USER\SOFTWARE\FLEXlm License Manager]

As the key is selected, in right panel ADSKFLEX_LICENSE_FILE will be visible.
Right click on the key and delete it.

Specify the license server in ADSKFLEX_LICENSE_FILE system variable

Go to Start > Control Panel > System and Security > System.
Select Advanced system settings.
On the System Properties dialog, click Environment Variables.
Under System Variables, click New.
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:

Go to Start > Control Panel > System and Security > System.
Select Advanced system settings.
On the System Properties dialog, click Environment Variables.
Under System Variables, click New.
Enter FLEXLM_TIMEOUT for the variable name and 5000000 for the variable value.
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:

Open a Terminal window
Type open ~ (Mac) or nautilus ~ (Linux) to open $HOME folder
Drag and drop flexlmrc.txt file from Desktop to the home folder.
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:

Click the Start menu and type cmd.
Right-click on the Command prompt and choose "Run As Administrator."
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.

Open Registry Editor (Start > type regedit > ENTER).
Navigate to HKEY_CURRENT_USER\Software\FLEXlm License Manager.
On the right-side, verify of the ADSKFLEX_LICENSE_FILE key exists. If yes, remove it (right-click > Delete).
Run the software again.
Select Multi-user in the Let's Get Started screen.
Follow the steps to connect to your license server.

Microsoft Surface Dial fails to pair with PC

One of the most interesting innovations that were released by Microsoft is the Surface Dial. This only goes to show that Microsoft is very competent not just in hardware but in overall innovation. Although it’s quite a piece of technology and as far as the consensus is concerned, it works pretty well, there are still some issues encountered by users. One of the particular issues experienced by users is that the Surface Dial fails to pair with every Windows 10 PC. At a time of writing, it is still not clear what the cause of the problem really is. However, their possible solutions are provided in this post that might help you resolve the problem. Before you get started troubleshooting the problem, make sure that there are two AAA batteries fitted inside properly.

Option 1 – Check if your PC supports Bluetooth 4.0 LE

In case you don’t know, the Surface Dial only works with the Windows 10 Anniversary Update and later PCs that support Bluetooth 4.0 LE. Thus, you have to check if this is supported or not before you troubleshoot further.

Tap the Win + R keys on your keyboard to open the Run dialog box.
Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
From there, click on Bluetooth and select “Microsoft Bluetooth LE Enumerator” from the drop-down menu. However, if it is not there, then it simply means that your computer does not support this standard which is most likely why you were unable to pair with other Windows 10 PCs. On the other hand, if you were able to see it, then proceed to the next troubleshooting steps below.

Option 2 – Check if Bluetooth is on

The next thing you have to do is to check if Bluetooth is turned on. As you know, the Surface Dial connects to your computer using Bluetooth and so you need to check if it’s really on or not. Aside from that, you also have to verify pairing.

Tap the Win + I keys to open Windows Settings.
Next, select Devices from the menu and click on Bluetooth.
After that, make sure that the toggle switch for Bluetooth is turned on.
Now all you have to do is to verify pairing by pressing and holding the pairing button located beside the batteries and then wait for a few seconds until the Bluetooth light begins to flash.
Then go back to the Bluetooth section and click on Bluetooth or other devices.
From there, click on Add Bluetooth and select Surface Dial.
Follow the next instructions on the screen and click on Done once everything is completed. That should fix the problem.

Option 3 – Check if Surface Dial is connected to another PC

If you think that connecting a Bluetooth device to two different PCs at the same time is wise, then think again as it does not really bode well for the overall user experience. Thus, you need to disconnect the Surface Dial from the system that you are currently using. On the other hand, if everything fails, then it’s most likely that the Bluetooth adapter is the one at fault. So you may have to get a third-party device that connects to your system via USB and then see if it works or not.

The server did not register with DCOM

There are times when after you upgrade your Windows operating system, the System Logs under the Event Viewer will display an error message saying, “Event ID 10010 error – The server did not register with DCOM within the required timeout”. What is DCOM? DCOM stands for “Distributed Component Object Model”. It is a proprietary Microsoft technology that allows the Component Object Model or COM software to communicate across a network. You can consider it as an extension of COM which is equipped with the capability of solving a couple of inherent problems related to the COM model to the better use over a network. COM is a tool that’s used for advanced configuration and troubleshooting in Windows 10. Developers usually use it to configure routine components and application behavior like participation in transactions and object pooling and so on. The Component Services needs the DCOM wire protocol in order to communicate with the Component Object Model components on other computers. By default, in a Windows-based system, the network computers are configured initially to enable DCOM. There are also some components in Windows that might require registering themselves with DCOM. However, if they fail to do so, you will encounter the “The server did not register with DCOM within the required timeout” error. To fix this, here are some suggestions you can check out.

Option 1 – Try to use the Component Services

Tap the Win + R keys to open the Run dialog box.
Then type “dcomcnfg” in the field and tap Enter to pull up Component Services.
Next, double click on the Computers folder located in the right pane and right-click on My Computer, and select the Properties option.
After that, switch to the COM Security tab under My Computer Properties and then go to the Access Permissions section.
From there, click the Edit Default button and in the new window that appears, apply the correct permission to objects under the Group or user names section.
Once you’re done, click OK and exit. This should fix the error.

Option 2 – Make sure that Function Discovery Resource Publication Properties Services is running

In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
Next, scroll down and look for the “Function Discovery Resource Publication” entry and double click on it.
Then switch to the General tab and from there, make sure that the Startup Type is set to “Manual (Triggered).
You also have to make sure that the service is running so if it’s not, just click on the Start button to start the service.
Now click on Apply to save the changes made.

Option 3 – Try resetting the default DCOM permissions

Tap the Win + R keys to open the Run dialog box.
Then type “dcomcnfg” in the field and tap Enter to pull up Component Services.
After that, expand Component Services > Computers and right-click on My Computer, and then select Properties.
Next, go to the Default Properties tab, and in the Default Distributed COM Communication Properties section, make sure that:
- Default Authentication Level is set to Connect
- Default Impersonation Level is set to Identify.
