Anyone have any good links on changing permissions options and such? I am unable to run an msi file since it says I need admin permissions when I am one and everywhere I look I am part of the administrators group but it still doenst allow some things. I also have an external drive that according to windows I will have to systematically have to change the permissions on each and every file. It will not even show me the security tab when choosing multiple files. This is with windows 7 pro.
