Teamviewer wont start

jon_hooper

Hi, I have a business licence and up until 14 Jul all was good. After windows update KB5015814 the problems started.

Now when Windows 11 Pro starts the teamviewer service starts and the process is running, however there is no icon in the tray nor will the application start if you open the app.

I've reinstalled several times and even moved from the 32bit to the 64bit version sith still no success.

Occasionally after restarting the PC multiple times the app starts with no obvious reason.

Any ideas??

Hello @jon_hooper,

Welcome to the TeamViewer Community! 😃

Please make sure your OS is up to date in the newest version. (You can check the complete lists of supported OS here.)

Also, I would advise you to check if Windows S Mode is turned on.

If it is, you may consider disabling the S Mode for TeamViewer to work normally again.

If this is not the case, let us know, and we can check other possibilities to troubleshot it 😉

Hi Carol,

Everything is up to date and Windows 11 pro doesn't support S mode.

I'm suspecting that KB5015814 has something to do with the issue.

Hi Carol,

Ticket raised but no solution as of yet. You would think they would offer temporary access to the webclient while the issue is being investigated. This is now impacting my business. Not impressed.

Downgrading teamviewer to 15.30.3 has restored functionality just in case anybody else is having this issue.
