I purchased a new 64bit computer with Windows 7. The major use for the computer would be to scan and store pdf searchable records using Nuance PDF. I noticed that a number of sites offer Office 2003 Professional for about one hundred dollars. I have plenty of experience with Office 2003 but I would like the Professional edition because I want to try to learn how to use Access. I understand that Office 2003 Professional should be useable on the new system if I install all the upgrades. Will installing Professional slow the speed of the scan and store operation? I do worry about getting a legal version of Professional. Would I be better off to install Open Office instead and buy the new Access separately?
