UAC not allowing software activation

Once again the so called support engineer did not even read the entire thread before posting yet another solution that did not do any good.

However, I was able to solve my situation without your help after all. My original question was how do I turn off UAC. the method suggested in this thread only turns the notifications for UAC off not the UAC itself. In order to turn off UAC completely,
I went into the registry and turned it off there. After doing this, everything installed perfectly.

Here is a link to read about turning off UAC:

DISCLAMER: Making edits to the registry is EXTREMELY dangerous and could cause damage to your computer. Consult a trained professional with any questions.
