My computer won't install JDownloader

Don't worry, you're not the only one. I've also attempted to install JDownloader (& JDownloader 2 beta) without success. I suspect it has something to do with needing to add antivirus and/or firewall exceptions, as MSE alerts me of a (hopefully false) positive during the installation of JD2.

I could try to sort it out or try an alternative downloader, but I really don't have the time (big test coming up on Thursday; I really should be studying more). We certainly don't want to turn this thread into JD tech-support. Anyway, I just wanted you to know you're not uniquely unable to install JD. There are plenty more idiots like me around who willfully or otherwise are patiently waiting for the torrent release.
