Add Printers doesn't see me as Administrator

When I go to the add printers option in  then I'm not able to add a printer.

Message "You must be an administrator to install or delete a printer!" is displayed.

I'm using win7 home and i'm the only one user on the system and i'm administrator.

Does any of you know what's going wrong here?


I seem to be having the same issue.
Windows 7 Professional, SP1

I've found an solution.

When starting PDFCreator using right mouse button then select 'RUN as administrator'.

Then PDF Print Monitor is seing me as administrator.
