Fix Error 1310, Error writing to file
If you were trying to install a program on your Windows 10 computer but encounter an error instead that says, “Error 1310, Error writing to file: <PATH>, Verify that you have access to that directory” then read on as this post will guide you on how you can fix it. This kind is a fairly common type of error encountered by many Windows users. You can get this error when you try to install certain programs like Excel, AutoCAD, Adobe Photoshop, and some other Adobe products on Windows. One of the most likely causes for this error is that the required files or location is already used by some other software which means that Windows finds that you are trying to overwrite a software that is already installed. Aside from that, it could also occur if the program installer does not have access to write to that directory. To fix Error 1310, here are some potential fixes that could help.

Option 1 – Clear up temporary or junk files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.
  • Open Setting > System > Storage from the WinX Menu.
  • From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
  • Next, find a link that says “Free Up Space” and click it to open.
  • After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
    • Windows Upgrade Log Files
    • The system created Windows Error Reporting Files
    • Thumbnails
    • Temporary Internet Files
    • Previous Windows Installation Files
    • Delivery Optimisation Files
    • DirectX Shader Cache
  • Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
  • Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix Error 1310.

Option 2 – Reinstall the program in a Clean Boot State

You can also troubleshoot Error 1310 in a Clean Boot state. It could be that there are some third-party applications in your computer that's preventing the program from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.
  • 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.)
  • After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the program again.

Option 3 – Try to unregister and re-register the Windows Installer Module

  • Tap the Win + R keys to open the Run dialog box.
  • Then type the “msiexec /unregister” command and hit Enter to unregister the Windows Installer Module.
  • Next, type the “msiexec /regserver” command and hit Enter to re-register the Windows Installer Module.
  • Now restart your computer and see if un-registering and re-registering the Windows Installer Module fixed the problem or not.

Option 4 – Take ownership of the location where you want to install the app

The next thing you can try to do is to take ownership of the particular folder as this worked for some users who experienced the same problem. But before you do that, you have to create a System Restore Point first, once that’s done, proceed to the given steps below.
  • First, locate the concerned folder and right-click on it then select Properties.
  • Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
  • After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
  • Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
  • Now edit the permission to Full Control for “Everyone”.
  • Click OK to save the changes made and then exit.
  • Finally, try to install the application again.

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.

Identify resource hogging applications
Resource hogging is a term when one single application or few of them are taking all system resources for themself causing extreme slow down in the computer and nonresponsiveness. It can be a very frustrating and time-consuming experience and it can cost you money if you can not finish work on time due to this effect. I believe that everyone has experienced at least one slowdown in their IT carrier because of resource-hogging applications and most users do not know how to deal with this. We are here to help you with this issue. Just to be aware that this method shown here is not a method to miraculously speed up your PC or anything similar, this is to be able to detect and recover from extreme slowdowns. Hardware components are still very important and if you can upgrade your computer if it is outdated, please do it because new applications will require a more modern system, and not any kind of tips and tricks will save you from outdated hardware.

Identifying resource hogging app

Now when we got that out of the way let's talk about slowdowns, it is no secret that sometimes an application has bugs and memory leaks that can cause this kind of behavior, and sometimes the application simply takes up too much memory for any other application to work normally. The most simple and straightforward way is to bring up a Windows task manager and inspect running applications and services. You can bring task manager by the key combination of CTRL + SHIFT + ESC If the system is in deep memory deficit you will have to wait for the task manager to open and show itself on-screen. Once opened, click on more details if that view is not opened by default. Once the view expands you will see all running applications with how much RAM memory have they taken and how much CPU they are using.

What to do with app?

Now you are presented with a choice on what to do with the problematic application. If you press the end task button on the bottom right, Windows will kill the application and its processes but any unsaved work inside the application will be lost and unrecoverable in most cases. Or you can try to remove smaller applications running to free up more memory and CPU in order for the computer to catch up. Any choice you make is up to you, but be very careful not to kill Windows essential service by mistake, that will cause immediate system instability with high chances of a system crash.
