In trying to print a PDF file I get the error message: "There is a problem with Adove Acrobat/Reader. Please exit Adobe Acrobat/Reader and try again." When I do, the same thing happens.
Last week I was notified by my computer that there was an update to the Adobe Reader to 9.3.1 which I installed. I did not have a problem printing PDF files before this update but I do not know that there is a direct cause and effect.
Adobe's response is that I'm getting all the help I've paid for in my free download.
You need to uninstall, clean up the installer and reinstall Reader.
Uninstall from the Control Panel (Add/Remove Programs in XP, Programs and Features in VIsta or 7)
Download, install and run the Windows Installer Cleanup Utility (msicuu2.exe) to remove the Reader 9 installer files as well as any previous versions which may be on your system.
Redownload and reinstall Adobe Reader 9.
It should work without errors after that.
Actually I sometimes would come across this problems like you but I still don't why the exact reasons. Always in this case, I would use Foxit reader for alternative. It is more easier to load PDF files I think. Or uninstall it and then download the latest version. This approach always works well for me.
