Re: To reinstall Acrobat 8 Upgrade I need to present previous versions e.g. 3 and then 4 and then 5 Upgrade every time. Is there no simpler way to validate my ownership?

Windows 7? Then don't waste your life minutes fumbling with an Acrobat 8 - Windows 7 combination.

If you are to be using Win 7 you'll need the current release of Acrobat (XI). "X" will function but it is no longer marketed by Adobe.

Be well...
