TeamViewer won't start up with Windows 10 21H1

kanishknishar

I am running Windows 10 Professional 21H1 19043.1110. My TeamViewer version is 15.20.6 (64-bit.)

I want TeamViewer to start with Windows 10 but no matter how many times I enable it from the options it won't work. When I restart the PC, the option becomes unticked and the app doesn't start. I am the admin/sole account on the PC. I have:

1) Tried opening the application as an admin.

2) Reinstalled the app (with Revo Uninstaller on Advanced to make sure no files remain.)

3) Clicked on auto (delayed start) in Services.

What should I do?

This issue resolved itself. It may indeed have been fixed by auto (delayed start.)

Hello @kanishknishar,

As you already tried all classic troubleshooting methods, there is definitely something conflicting in your system.

The worse case would be that apps like Revo Uninstaller broke something... We do not recommend using these apps for software uninstallation.

We recommend using the following methods:

What you still could do, is to check if the auto-start key is existing in your registry.

The key is called Always_Online.

Is it located in your registry in

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\TeamViewer

If the option is enabled, its value should be 1 (as below).

I hope this could help. 😊

If not, do not hesitate to ask your questions here. 👇
