Acrobat Elements - reinstall problem

I was unable to create pdfs using Acrobat Elements. As per previous posts I tried uninstalling Adobe Reader, rebooting, uninstalling Elements, rebooting, and reinstalling Elements 6.0.  I renamed the msi file also.  It got to the point where the installation could not write to c:\documents and settings\all users\documents.  I tried opening that folder and I get "access denied".  I'm the admin of my laptop so I should not be getting this.  I can't do anything with this folder and apparently, Elements needs to write to it.  Any suggestions?  Thanks.
