TeamViewer and Windows 11 (22H2) Update

I have problems with Windows 11 and unattended access

I have Windows 11 Pro - 22H2 on one machine and Windows 10 Pro 21H2 on another. The latest version of TV is installed on both, both are granted with Easy Access.

I can use the Windows 11 machine to start an unattended session to the Windows 10, but I cannot start an unattended session from the Windows 10 back to the Windows 11 machine. Windows 11 just does not want to accept the connection.

I can also start an unattended session from my ipad with the Teamviewer app to the Windows 10, but not the Windows 11. The connection issues are only when I try to connect to the Windows 11 machine

If I try one of the other methods such as - Remote Control - "prompt for confirmation" from the Windows 10, I message does pop up on the Windows 11 to allow the connection. But after clicking Allow, nothing happens. I just get a message on the Windows 10 that it is waiting for the request to be accepted, after a few seconds that goes, and the connection is authenticating message is displayed, again for a few more seconds before it then times out also.

Yes, the roll back to version 14 and then update to version 15 worked.

I see there is a new build the apparently solves the problem also.

Martin.

Hi Josh,

Thank you for your suggestions that downgrade version 15.35.7 to version 15.35.5.

My connection issue is solved, and I can now use my MacBook to connect to my Windows 11 desktop.😁

All the best,

Xincheng

I am trying to connect to one of my computers with unattended access, got the same message.

From this computer I can access any other my computers, but no one could access to this one.

OS on this computer is Windows 11, issue started about 2-3 weeks ago

!!!!!!!!!!!!!!!!!!

FYI, this is an ongoing problem with version 15.35.7. I've filled a proper bug report with TV support. I'm sure they'll get it fixed soon.

In the meantime, the fix is really simple

A) On the existing broken install, Extras->Options->Advanced, set to never check for updates and no automatic updates. Click OK

B) Uninstall existing TV, don't check the delete settings button

C) Reinstall an older version. Through testing I know 15.33.7, dated August 22, 2022 works. It's impossible to download an exact specific previous Teamviewer version from a trusted source so A) maybe you downloaded it recently to a client's computer and can grab your own copy from there, B) [removed per Community Guidelines - please do not download TeamViewer from third party websites]

Hello everyone,

Thanks for your patience in this matter.

The update file has been pulled from the updates as well as our main website while our developers work on the issue.

Affected users can download version 15.35.5 via our main downloads page.

We apologize for any inconveniences.

rolling back fixed it for me. thanks.

I finally broke down, removed v15, reinstalled 14, and let it upgrade to v15. It's working again on those two systems.

Previous Versions

With TeamViewer, you can control remote computers within seconds. Just download and get started!

After updating to 22H2 remotely the computer was running, but was not accessible any more.

Going local, I found TV was missing its TV account password - so unlicensed.

I typed in the password, got remote again and everything was fine. It appears the ID did not change.

However, after shutting down the computer, it was no longer accessible for Wake-On-LAN.

Hello,

I am experiencing an issue with remote control to Windows 11 22H2 version. Connection initiates but it never completes. Event logs show that TeamViewer app has crashed. Same with QuickSupport. Same issue on 2 different laptops. Both are AAD joined. Any ideas?

Hope will fix soon for 22h2 users

Same issue on 11/3/22 on Windows 11 22H2 on both source and destination PCs running TeamViewer v15.35.7

We're finding computers running TeamViewer are not showing in our TV administrator consoles as being online, they appear offline and we are unable to connect to them after the 22H2 upgrade. We have to add them back and their TeamViewer ID is now different to the one they had prior to the Windows update.

I have tried and still have issues with a computer that automatically updated 22H2. Since they are out in the field my question is there a fix soon as some as some of my connected devices have updated and I can't login to roll them back.

Installing TV14 worked for us. Thank you!

If by new build you mean the 15.35.7 build from the insiders, I can confirm, this does NOT work as well. I find it funny how the post above says they tested the basic features of TV on Windows 11 H2 and they all passed but let's be real. The basis features are remoting into a system isn't it? That ain't working...

I beleive I found a temporary solution to the Windows 11 22H2 problem I described above:

• Uninstall TV 15 including all settings
• Download and install TV 14
• Use "Check for a New Version" feature and allow TV 14 to upgrade itself to TV 15

I can now remote control a Windows 11 22H2 machine

If I had to guess, I think the lastest TV 15 install has a problem with one of it's components or fails to update another Windows component correctly. Install TV 14 first seems to correct the problem.

Please let me know if this "fix" works for others.

Same issue as many people above

I'm running Windows 11 Pro 22H2, and it won't accept incoming remote control connections (IPC Error). I verified that I can connect FROM the Windows 11 machine TO a Windows 10 machine and a macOS Ventura machine. But I cannot connect from any other machine TO the Windows 11 Pro 22H2 machine.

I have tried disabling UDP and running TeamViewer as administrator but no luck.

Any thoughts?

Hi,

I have a similar issue, using Windows 11 (home edition - 2022H2) and lost the connection after upgrading to H2.

Please let me know if the issue is going to be resolved.

I have a similar problem as DaveC9. My windows 10 PC is connecting to windows 11 (22H2) but does not display anything. Windows 11 shows that connection (session) was successfully established but windows 10 machine does not invoke viewer. I have no issue connecting from windows 11 PC to windows 10 PC. Both PC have the latest version 15.34.4 (64 bit) of TM.

We recently installed TeamViewer, Version 15.35.7 (64-bit), for our company, but as an administrator I cannot connect to any computers remotely. We have tested trying to re-start the services, first on the remote computer, with no luck, then on the computer trying to connect. Still no luck. Could there be any configurations I missed during set-up? I am noticing a Fatal error during installation (0x80070643) in our EndPoint app install status.

Tried also to use Remote Terminal from Win 10 to Win 11 machine, but when the terminal opens you cant fill username and password, everything is not fillable, you can just look at window and then close it. Please fix, no use like that.

Trying to connect from me (win 10 team ver 15.35.5 32 bit ) to friend with win 11 22h2

(team ver 15.35.7). No connection, no message, just locks up.

Tried to upgrade my own version, says I alreday has latest version.

Having no trouble at all with other win 10pcs.

See on the forum that 22h2 is "under review",

Any new developemts in this matter ?

regards

I cannot connect remotely with password from Win 10 22H2 to Win 11 22H2, few sudden times it has succeeded but don't know why, from iPhone teamviewer remote connection to same Win 11 machine works every time. So there is something wrong with PC client.

Similar connection from Win 10 to Win 10 machine works ok.

So frustrating, please fix.

Those rare times it works, sometimes it takes really long time to get the remote display, sometimes it comes immediatelly. You can see the session information at the remote machine but never get the display at calling machine. Sometimes it just close the connection.

Win 11 Home v22H2 64Bit system with all updates in both ends and TV.

I am totally unable to connect to a colleague who is using Windows 11 Home 22H2 and he has TeamViewer 15.35.9 (64 bit).

We BOTH get an error message:

"Unable to connect

Either your partner isn't connected to the internet or your partner's TeamViewer isn't running yet

Please tell your partner to check their internet connection or to start TeamViewer"

We both have excellent internet connection and always have had. BOTH of our TeamViewer is running.

So why can we both NOT get connected. This is the absolute WORST time I have ever experienced with TeamViewer in 20 years of usage.

Help US sort out this serious problem.

Thank you

Installing TeamViewer 14 also worked for me. Latest TV15 x64 still did not solved the problem. Upgrading from TV14 to TV15 is still working.

I can get into other computers that have installed the host software no problem.

I am the admin, I upgraded to the latest version in my office and at my home.

Now is throwing me the error constantly: connection not established, authentication canceled

I am using Easy Access

I needed for someone to turn off and restart TeamViewer completely in my office PC to make it work, but as soon I disconnect or machine goes to stand by, when it wakes, does not let connect.

Version 15.35.5 (64bit)

using corporate: 3 channels

Hi all, I'll add my voice to this issue, no problems at all until Teamviewer update occurred on both machines (Host and remote). Paid account, connection OK via [Third party product], absolutely zero information or comment other than 'restart' the service even when both ends have been restarted or powered up, great stuff TV!

And also just upgraded to v15.35.5 without issue as well. Definitely the 15.35.7 version that's causing the issues.

Just pulled client version 15.33.7 and re-installed on the Windows 11 host. Workaround successful and I can now connect w/out issue.

I'm looking forward to a product update to fix the issue with the latest available build.

Thanks to all who have posted this workaround.
