There was an error rendering this rich post.

PROBLEM DESCRIPTION: It has been happening for some time now that the connection made with TEAM VIEWER (with administrator user) to computers (with WIN10 64bit OS) of various non-administrator users NEVER completes the cycle useful for the connection

SIDE MY TEAM VIEWER
1) I enter client computer ID
2) I enter Administrator credentials

SIDE TEAM VIEWER QS REMOTE USER
1) the TeamViewer window disappears the window/consent to restart Team Viewer with adm user does not even appear staying on hold for a long time
Cannot connect how can I solve the problem?

below I copy-paste the last lines on "TeamViewer15_Logfile.log" present in Roaming

________________________________

I realized that it could be a problem of the client user (who does not have administrator rights and is managed by domain server , so it is not a Microsoft user)

so client side I deleted the folders

C:\Users\UTENTE\AppData\Local\TeamViewer

C:\Users\UTENTE\AppData\Roaming\TeamViewer

and tried again the connection however without success

I ask: what in the folder C:\Users\UTENTE, can block the restart as adm from remote ? ??

or what else affects the failure to restart TeamViewer?

ADM SIDE
on my computer TEAM VIEWER version 15.64.3

CLIENT SIDE (the client user does not have administrator rights)
on remote client computer TEAM VIEWER QS version corresponding to the one I use

NB both the ADM user and the remote client user are managed by a domain (they are NOT Microsoft users)

ADM SIDE (with Team Viewer )
1) I enter the client computer ID
2) I enter Administrator credentials

CLIENT SIDE (with Team Viewer QS)
1) the TeamViewer window disappears

but the consent window for restarting Team Viewer never appears (what can block the appearance of this consent window?

so I can't connect as ADM
this only happens on some computers, on all the others the connection occurs

First, ensure that both your computer and the remote machine have the latest version of TeamViewer installed. Compatibility issues can arise if different versions are being used. Next, check the User Account Control (UAC) settings on the remote computer, as high UAC settings can block applications from running with elevated permissions. Lowering the UAC level temporarily might help. Also, verify that TeamViewer is configured to start automatically on the remote machine, as this ensures the service has the necessary permissions to restart with admin rights.

You can also try manually running TeamViewer as an administrator on the remote machine by right-clicking the TeamViewer icon and selecting "Run as administrator." Additionally, check whether security software, such as antivirus or firewall settings, is blocking TeamViewer from restarting. Temporarily disabling them can help determine if they are the cause of the issue. If you're using TeamViewer QuickSupport, consider switching to TeamViewer Host, which is designed for unattended access and might handle admin privileges more effectively.
