msra.exe bad image error citing tv_x64.dll Windows 10 1903

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.

Hi all,

One option might be to disable the hooks for TeamViewer with the following registry key:

Please restart the TeamViewer service after importing the key.

Cheers,

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).

Tried that link and got:

Can we get the registry fix back? The link is empty.

The link is dead. Please can you provide a new one or just the registry keys? I really need this solution. Thanks.

Add the following registry key in your Windows computer.

Location: HKLM/sofware/wow6432node/TeamViewer/
Type: D-word 32 bit
Name: EnableHooks
Decimal value: 0

Then restart TeamViewer service and try again.
