PPSSPP crashes at launch

Then as mentioned earlier it might be graphics driver. You can try editing ppsspp.ini and change GPUBackend from 0 to 1, or switching at your other pc and copy the file if it crashes before creating one.

There are no open source windows drivers so it's just some hackish mod which might as well be tailored for one app breaking stuff for all ppsspp backends. But also XP64 was always known to be awful when it comes to compatibility and there had to be a reason for that, it's WOW64 might simply be buggy meaning you're out of luck on that system.

If you can't change OS on that pc, you could still use some linux distro from pendrive to avoid mixing modern software with OS that remembers dinosaurs.
