Well, I'm an idiot. I installed parallel tools for bootcamp before getting build 3106 (thought I needed them for some reason). Then, when it told me to uninstall them, I couldn't figure out how (PLEASE put an uninstaler WITH the download), so I deleted the "parallels tools" file and all folders I could find with the word "parallels" in them. It still told me to delete them, so I thought I'd give it another shot and went to reinstall the tools. That's when I realised that you re-download the installer to uninstall (uhhhh...????? Would be nice to be told that, and better to get an uninstaller with the dl in the first place...). Now, however, it won't uninstall because it can't find the files I deleted (cause they're gone), but it won't reinstall. ARG!!!!! Pleaes help! Edit: Did a system restore and fixed this problem, but had others later, so just did a full windows reinstall. Problem solved.
