That is really strange, but I don't experience any crashes. Tried to recompile EXE and include it into installer, but not sure it will help.
You have tried different campaigns I guess? What if COHOKUM1162 will be renamed into COHOKUM? just in case you have some installed software configured for this particular name (like Nvidia graphics settings)
Also rename EECH.INI temporary, so game will create new one, maybe some ini settings cause issue.
