Zip/Jar Download Available?

Is there an alternative download for those without admin permissions?

Currently my only computer available is one that I borrow. I'm not given admin permissions for obvious reasons. I could ask the owner to download it for me, but they usually don't have time to help me install every little thing like this. The point is, I was wondering if there's an alternative way to download this software. If not, would it be possible to make an archive type of file available?
