I used Mo2 for many month without major problems.
Now I have tested some new animations and started FNIS a lot.
Suddenly FNIS did not not found the game data any more.
FNIS started but displayed all the options for Oldrim.
I reinstalled FNIS and that did not help. Furthermore I discovered that every third party tool started but gave an error like SSE and Loot just like FNIS
Mo Log shows this for FNIS :
22:30:29.718 [I] injecting to process 8452 with different bitness
22:30:29.719 <6688:9208> [E] failed to inject into "G:\Steam\steamapps\common\Skyrim Special Edition\data\tools\GenerateFNIS_for_Users\GenerateFNISforUsers.exe" : Unknown exception
The thing with bitness.... could point to FNIS showing Oldrim options.
Running Windows 10 64bit...
Any idea ?
