Does Office appear to install every time you try to open a document or you see a configuration dialog.
Open run (Press Windows Key + R) and paste in the correct line for your version of Office and the troublesome application.

I permanently face that behaviour (perpetual installs) when executing word and excel 2007.
Adding the NoReReg key in the registry has solved the problem for WORD invocation, but the wrong behaviour still exists for EXCEL.
Any other ideas ?
Best regards.
