While trying to play an application installation disc on my CD/DVD drive today I got the following error message: 'This file does not have a program associated with it for performing this action. Create an association in the Set Association Control panel.' I have no idea what this means. WHERE is the Set Associaton Control panel and HOW do I create an association or respond to this message. I have a Dell Inspiron 530s,...Vista OS...3 GB ram.
