A.J i'm with Aries on NOT editing the registry unless you have done so before, and you are comfortable with doing so. i would correct one thing though. once the registry search has found an item in the left pane and the hi-lited item says camtasia just delete it(the items in the right pane associated with it will also be removed), if the item in the left pane does not say camtasia then look at the items in the right pane and only delete the ones that say camtasia leaving the rest. if the registry search lands on something in the left pane that doesn't say camtasia and nothing in the right pane doesn't say camtasia do no delete that item, just search for the next item. the windows registry will a lot of the time show you an item that has nothing to do with what your looking for, and deleting the unrelated item can have unforeseen consequences. good luck.
