We have been testing FMRTE with the latest update for Windows 10, the Creators Update, and FMRTE works just fine.
But if you have any issue starting FMRTE in Windows 10 - Creators Update, make sure that you don't have RivaTuner installed, and if you have, please keep reading this post.
RivaTuner 6.6.0 and previous versions are causing some issues in some other windows apps in the Windows 10 Creators Update.
Unfortunately, FMRTE is one of those apps, but don't worry, there is a fix for it
To fix this, you have 3 choices:
Exclude FMRTE from RivaTuner, so it won't mess with FMRTE, and FMRTE will work normally
Update RivaTuner to the latest beta version (7.0.0) that seems to have this issue fixed
Uninstall RIvaTuner
How to exclude FMRTE from RivaTuner
Open RivaTuner, and Add a New Application Profile (press the + button)
Select the FMRTE executable (fmrte.exe, usually located at c:\BraCa Soft\FMRTE 17)
Set Application Detection Level to 'none'
