I have been using Acrobat Pro 8 with Windows 7 for many years without any problems, but all of a sudden, when I print to the Adobe PDF printer from most applications, the "Save PDF file As" dialog box appears and immediately freezes - nothing happens if you click the Save button or if you try to type a different filename, and the application I was in, whatever it was, also freezes, so that I have to go into Task Manager and kill the application.
I have tried deleting and reinstalling the Adobe PDF printer driver - and have even tried completely deleting the Adobe driver first, and I have tried running Repair in Acrobat, but none of these things help.
I can still print using the Adobe PDF driver from other Adobe applications (including from Acrobat itself) but not from any other application I've tried.
I can still create PDFs from any application using the Bullzip and CutePDF drivers, however.
Sorry for the delay in response.
I am not sure whether this will be a compatibility issue or other issue related printing. Adobe Acrobat 8 was never tested with Windows 7 from our end. It somehow feels like the issue might be related to Acrobat 8 activation, you may try to install Acrobat 8 from this link: Activation or connection error when starting CS3 or Acrobat 8 and do check there should be a new serial number as well for Acrobat 8.
Let us know if that helps.
