We use TeamViewer to remote to a computer offsite and then use Windows Remote Assistance to help staff at that remote site as we don't have TeamViewer installed on all computers. Prior to installing Windows 10 1903 we had no issue using remote assistance. Since updating to 1903, windows remote assistance no longer works. Receive msra.exe bad image error noting C:\Program Files (x86)\TeamViewer\tv_x64.dll is not designed to run on windows or contains an error. We receive no errors with RDP only MSRA
I've uninstalled/reinstalled TeamViewer and still receive the error. Has anyone else seen this issue or know of a solution.
I forward this to our development and will get back to you as soon as I received an answer :)
We found that disabling UAC was causing this issue in v1903. We had a GPO/policy in place that set the following key:
:: DISABLE UAC
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v EnableLUA /t REG_DWORD /d 0x0 /f
Once we enabled UAC again (set to 1) and restarted the machine we were able to use Remote Assistance (msra.exe).
One option might be to disable the hooks for TeamViewer with the following registry key:
Please restart the TeamViewer service after importing the key.
