If this is in the wrong section, please move.

I am trying to update Open Office. It get to the install part and it tells me it does not have permission, please log on as administrator. I am the administrator. Under users it has my name and computer administrator. There is one other use on my laptop, but he rarely uses it.

How can I get the program to finish installing if I am already logged in as admin? Thanks!

This is on my laptop.
