Just a few days ago, Adobe Reader XI and Acrobat X stopped opening. When I try to open a pdf or either one of these programs the cursor would show a busy icon for a few seconds and stop. Each time I open it a process will show up in task manager, but no window will open. I have tried these things, but none will work Restarting the computer Running as Administrator Repairing the installation Reinstalling Following this guide: http://helpx.adobe.com/creative-suite/kb/acrobat-failed-launch-30-days.html When I ran acrofix it returned exit code 3 Also I have seen this, but I am not running tune up: Adobe Reader XI will not launch I am running windows 7 ultimate x64. Can someone help? Thanks!
