I installed Homeworld Cataclysm on my Windows 10 machine, applied the 1.01 patch, and tried recommended command line settings I found in various threads online, such as cataclysm.exe /heap 256000000 /enableSSE /triple /disableAVI /safeGL. One recommended thing I wasn't able to do is set compatibility options to NT, which isn't available as an option in the compatibility settings, but I tried other compatibility settings (Windows 95, 98, XP SE2, XP SE3). I'm also running it in administrator mode.
Right now, what I see is that the game doesn't even run. Upon double clicking nothing happens except that Windows brings up a dialogue box asking if this program was installed correctly and if I want to do compatibility troubleshooting.
From reading other people's accounts, it sounds like most people are, at the very least, able to get it to launch. What am I missing?
