Machine has two user setups (Admin and user). When logged in as "user" and trying to run Internet Explorer there pops up a quite empty screen that says that system does not match for minimum specifications or something. Safari works so why not IE?

I am not at work at now to tell what it said exactly, but when I logged in as an administrator it worked when I set from IE's preferences "home site" as "none". However I am stuck what to do when logged as "user", since it won't let me start IE at all.
