solution for this problem is not to only run NetUserC2.bat file from caesar ii folder. You need to open NetUserC2 file and paste dll files wich should be registred.

Just continue existing regsrv32 lines save the file, run it.

REGSVR32 /s projectmanager.dll
REGSVR32 /s pisogen.dll
REGSVR32 /s pod.dll
REGSVR32 /s ImportExport.dll
REGSVR32 /s MaterialData.dll
REGSVR32 /s pipeline.dll
