No.

Yes, you have to go out of your way to Run As Administrator (RAA). However, regardless of how you initially encountered a problem, once you did that there could be any number of files contaminated with permissions issues.

Specifically, I said to delete your 3.5 personal package library, but your description is not specific so I suspect you may not have done that. However, any file modified by you intentionally or not while using RAA could be causing your problems now, so now it is up to you to find those files somehow.

I doubt the "team" will spend much time looking at this based on your descriptions so far. They need something reproducible, and the fact that you already used RAA to "fix" the problem makes anything you did prior to that almost impossible to reproduce.
