I have two accounts set up on this machine. One is me, and I'm an admin. The other is my brother and he's a regular user. I installed Adobe Acrobat reader and I want PDFs to be associated with Adobe reader. Under my account I right clicked and hig get info changed hit and hit change all. I can't do that under the other account. Adobe reader isn't a choice, I can't tell it to use Acrobat reader. Is there a way to change this for ALL accounts, not just mine?
