P3DO crashed on my XPHome constantly, but I grabbed the latest version and all is okay now. One of the problems seemed to be folders with a file with no .rsr or .png. Then there would be folders with .pngs that it didn't like. The crashes were always graceful though. Windows would close it and I'd just run it again. I just use it for making pngs from rsrs and rsrs from pngs. I keep both rsr and png. don't ask.
