Yeah there were a couple of issues, one is DEP, data execution prevention. Older versions of the compiler executed some data segments, so that doesn't work, unless you set an exception for the EXE in windows. Also try to run in XP mode. Generally, in a 32 bit environment there's a better chance. Also because of the millisecs system timer in 64 vs 32 bit, that caused problems I fixed only in the 2021-reloaded release of the engine..
