So far I have installed 3 different Windows Professional operating systems after clean formats. First I installed a Windows XP Professional corporate, then I installed a Windows XP Professional 64-bit corporate and finally most recently I installed just plain Windows XP Professional.

I've already asked a few people in personal messages about this, but I can't seem to get a definitive answer (if it's possible, and if it is how to do it).

I want to download a free (Let me reiterate I mean FREE, like originally free, not the illegal copy) drawing/graphics software. You know, like Corel Draw, Paint Tool Sai, Adobe Illustrator, and other softwares. Here is the catch: they all need Administrator privileges and some, passwords! I cannot access the Administrator for my own reasons.

Anyway, does any of you know a drawing/graphics freeware that doesn't require Administrator rights?

Thanks guys.
