Trouble with 2003 Busch Series TRG carset

[Random Classic]

So, I'm having a little bit of trouble with the 2003 Busch Carset that TRG made. (Big thanks to kirbyfighter12 for having it in the encyclopedia BTW) When I try to run the exe, it pops up saying something about the program being too big for memory, And closes itself. Any idea why this is happening?
