Hi Rave,
Thanks for this; my issue is that I have now supposedly purchased a retail version of Acrobat X1 (i.e just spent more $$, after the upgrade attempt to Acrobat X1 failed), and while this feigns an OK install, it fails in someway to override the "Upgrade Acrobat X1 version". E.G. once I load up to read an acrobat file the "upgrade version" executes/intercepts and ask for serial numbers and check for a previous qualifying version which I do not have, (BUT what I do have is the current retail version of acrobat X1 which is not recognised)
Do I need to uninstall and start over again? (I am reluctant to do this as I am sure serial number issues will arise, as I assume downloaded file will be cleaned up etc, and I am not spending more money trying again!)
Any suggestions?
