Problem installing McAfee Vista optimizier

I purchased the Mcafee Windows Vista Optimizer to try and fix some of the recurring problems with Vista. However, I can't download/install this program. Everytime I try, as soon as the installation wizard comes up, I get the following message-- Internal error: failed to expand shell folder constant "userappdata"


Can anyone give me any advice on what is causing this problem and how to fix it?
