Hi bretsvoboda,
For file mismatch errors, if you check the following file path, can you first confirm the file version of the MultiplicityConfig file is exactly the same on both devices (properties -> details -> file version)?
- C:\Program Files (x86)\Stardock\Multiplicity\MultiplicityConfig.exe
After doing so, please make sure the Multiplicity process itself is running on your Secondary PC (can check from taskbar and try restarting the Multiplicity process there). If an issue remains, you could try reinstalling Multiplicity 4 (from your Stardock account) on both PCs and rebooting. Doing this will help ensure you've downloaded and installed the same update and without any errors.
From there, you'll want to double check you've added the connection to your grid correctly, that the Multiplicity process is running on both the Primary and the Secondary computers, etc.
If you're still experiencing a problem from here, a more complete "purge" of all files can be done. This should be the best way to ensure a complete removal of all files (such as anything lingering from a very old installation):
Again, you can double check you've added the connection to your grid correctly, that the Multiplicity process is running on both the Primary and the Secondary computers, etc. If any specific settings changes seem to be causing the problem, please let us know what exactly you change from default settings that may be causing any trouble.
Please let us know if these suggestions help to resolve the issue.
Best regards,
