I have verified that the installer for Acrobat 9 under http://prodesigntools.com/all-adobe-cs5-direct-download-links.html for Windows English did not work with the Acrobat 9 serial number. I remeber this was a common issue with the Acrobat installers being very specific regarding the serial numbers they accepted.
ALTHEBRACK I looked up the account information from your profile but it appears you only have Acrobat 8 Professional registered. Please feel free to e-mail me at <E-mail address removed>. If you can please include your Acrobat 9 Standard serial number and reference this thread it would be appreciated.
