for some odd reason i cannot extract 0.75 on XP.
Sorry that's partly my fault. I used a different compression method for the zip this time (LZMA) so assuming you're using the uncompression default utility provided by xp, you've either run out of RAM for extracting it or for some reason it's not supported.
I've re-uploaded the installer in a zip that should work for you. The alternative is for you to download the free 7zip software (which I highly recommend regardless).
Let me know if you still can't extract it after doing one of those two options.
