I have installed Adobe Acrobat Pro 7 on our system. I later installed Adobe Reader 7, and during installation I was asked which I wanted to open PDFs. I chose Adobe Reader. However, the default application for PDFs is still on Acrobat Pro. When I try and change this (through File Types...) as local or a domain admin, the setting doesn't save, stick, stay - whatever you want to call it. I can click OK on these options, go back into them and find it is still calling Acrobat Pro.
Any ideas? Full marks to go to a quick answer.
