I am using a desktop pc and a notebook. I have bough a MS Office 2007 and I had not issues installing the software in my notebook with Windows Vista. This was a little over some years ago. Right now, I have bought a new Desktop Computer with Windows Vista and tried to install the same ms office 2003 software, but I started getting this error "Setup cannot find proofing-en-us proof fr/proof.cab." Can anyone please help me out?
