Windows 10 is the second most popular Windows version among users and many large software companies created programs that are compatible with it. One of them is TeamViewer, which users reported they’re unable to use after they upgraded their systems to Windows 10.
How to fix TeamViewer issues on Windows 10?
1. Lower screen resolution
Before we start with doing complicated things, we should try out simple ones. Some users report that they didn’t have any problems on the previous OS version, but after they went for an upgrade, the screen went black every time they tried to access another computer. They reported that they just lowered the screen resolution of the host computer, and all the problems were solved.
2. Tweak your Registry
But, if changing the resolution doesn’t help, you should do one registry tweak. Make sure there is a dedicated Registry key for TeamViewer. If there is no TeamViewer key, create a registry key as an alternative workaround for running the software properly. Here’s what you should do to make an alternative workaround:
- Create “DisableDuplicationAPI” as Dword, a value of 1 (if you don’t know how to do that, look for Microsoft’s support)
- Click Start, type regedit in the Search box, and then hit Enter
- Go to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432NODE\TEAMVIEWER
- Go to File, Export and than add “DisableDuplicationAPI” to your registry
- After that, close the Registry Edit window
- Click Start, type services.msc in the Search box, and then press Enter
- Find TeamViewer process, right click on the service, and hit restart
3. Run the Windows Troubleshooter
If you downloaded TeamViewer from the Microsoft Store, you can use the built-in troubleshooter to automatically identify and fix general issues affecting Windows Store apps.
Go to Settings > Update & Security > Troubleshoot > scroll down to Windows Store apps > run the Troubleshooter
Launch TeamViewer and check if the app runs smoothly now and you have access to all its features.
4. Update Windows
Make sure that you’re running the latest Windows OS updates on your machine. As a quick reminder, Microsoft constantly rolls out Windows updates in order to improve the system’s stability and fix various issues.
To access the Windows Update section, you can simply type “update” in the search box. This method works on all Windows versions. Then go to Windows Update, check for updates and install the available updates.
After applying one of these solutions you should be able to run TeamViewer in your Windows 10 without any problems. But if neither changing the resolution or making an alternative registry key didn’t help, or you have some other comments or suggestions, we would like to hear that from you in the comment section below, so please express yourself if you want or need to.
You should know that TeamViewer was recently updated with improved Windows 10 support, so it might be a good idea to download the latest version now. Also check out this older article which contains some suggestions that might still be helpful.
