This error occurs when M-Files is looking for registry entry under an incorrect or missing version. This can be caused by leaving the Admin Tool or another service running during an update of M-Files.

2     Solution / Workaround

You can resolve this by re-registering the M-Files API and then restarting the M-Files server or services.

To register API run command prompt as an administrator and run following commands:

Regsvr32.exe "C:\Program Files\M-Files\<version>\Common\MFilesApi.dll"

Regsvr32.exe "C:\Program Files\M-Files\<version>\Common\MFilesApi64.dll"
