I have design Suite Standard installed on Windows 7 (62-bit). Acrobat suddenly stopped working. Everything else in the Suite works fine. Several reboots didn't help, so I uninstalled it and tried to reinstall (clicking on only Acrobat X). When I input the serial number, I got the message that the s/n was invalid. But it is correct.
This is not the first time I have had to uninstall and reinstall Acrobat X from the CS6 Suite. The program works fine on a second computer, which is the only other place the Suite is installed.
I have no other versions of Acrobat or the Reader installed. Also (and I suppose this is normal) among the Programs listed to Uninstall, Acrobat only stands on its own. The others are all under "Adobe Cretive Suite CS6".
I am really stuck.
