2GB is a hard limit in Win95, the OS simply didn’t support more back in the day. You might be able to kinda hack this game to run (copy all files to a huge ISO image, copy that to a 2 GB D: drive, mount that iso from within Win95 booted from a C: drive) – but I’d strongly suggest you simply get the Android port from Beamdog. It’s not cheap (10 bucks), but there are zero microtransactions, and all their ports are really well made (also BG 1&2, IWD, NWN).
