Out of memory errors running K40 Whisperer on Windows XP

Is there a fix or tweak available for 32-bit memory limitations? The laptop I have available to run my laser is an old Windows XP machine, I installed v0.92.3, when I try to load larger files I get “Memory Error: Out Of Memory” errors.

I was able to run a 3x3-in burn with no problems, but a 7x7-in burn is popping the error.
