Okay got TexGEN64 running, 50% goal
Texgen64 and Dyndolod64 are started from Vortex with arguments, here texgen64 is okay with the arguments and dyndolod64 show the registry key bug.
-m:"D:\Users\ew-te\Documents\My Games\Skyrim Special Edition GOG\"
-p:"C:\Users\ew-te\AppData\Local\Skyrim Special Edition GOG\plugins.txt"
-d:"D:\Program Files\GOG Galaxy\Games\Skyrim Anniversary Edition\Data\"
Had a look in the logs folder, placed 'Notice=1' into the DynDOLOD_SSE.ini, begging i got a log from it. The game registry key seems to be here and i dunno if this is something new?
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\GOG.com\Games\1711230643
Next question, why is TexGEN64 okay with the -d argument and DyDOLOD64 has a problem with it?
