Well for one, ENGIMA's setup currently does not support XP because of its lack of environment variables to installation paths that do not contain spaces.
Simple fix, go to the following line in your local copy.https://github.com/enigma-dev/enigma-dev/blob/master/settings.ey#L40
Change it to the following.
Then go to the root drive, you can optionally switch C: for whatever drive, and make sure the ProgramData folder exists there, if it doesn't then create it.
Then restart ENIGMA, and the issue should be resolved.
