Adobe Reader XI and Acrobat X have stopped opening. When I try to open a PDF, or either one of these programs, the cursor shows a busy icon for a few seconds and stops.

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

  1. Restarting the computer
  2. Running as Administrator
  3. Repairing the installation
  4. Reinstalling
  5. 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
  6. Also I have seen, Adobe Reader XI will not launch, but I am not running tune up.

There is nothing in Event Viewer for either Reader or Acrobat either.

I am running Windows 7 Ultimate x64.

  • Anything in your Event Log? – Rhys Gibson Jul 23 '13 at 2:56
  • Where should I look in Event Viewer? – ayao1337 Jul 24 '13 at 0:38
  • Try under Windows Logs|Applications – Rhys Gibson Jul 24 '13 at 1:54
  • I went through all the tabs in Event Viewer, but I could not find anything on Adobe Reader or Adobe Acrobat even after opening it and refreshing Event Viewer. – ayao1337 Jul 24 '13 at 2:05
  • Do an ALT+Tab to see if there is a user agreement you need to agree to, which might be hidden. – Steve Jan 13 '14 at 1:45

Adobe now has an official fix for this problem.
Download Acrofix here.

I had the same problem. It was frustration having to use internet browsers to read PDF files. Until one day, I tried to open acrobat reader XI again and the user agreement came on. I clicked agree and everything is running fine now. Do you remember the user agreement coming on after a successful re-installation?


I just had the same problem and this answer helped, thanks! To force the appearance of the user agreement I opened EULA.EXE by double clicking, which should be located in C:\Program Files (x86)\Adobe\Reader 11.0\Reader or a similar path, and accepted the agreement and now everything seems to work.

  • This does not look like much of an answer. To make it more like an answer and less like a comment, I think you should rethink and rewrite a bit. – user260419 Apr 13 '14 at 11:42

A little bit later, I found my answer. I had this same issue with Adobe Reader and Acrobat. It was not the EULA. I was messing with the task manager and I realized that killing the process acrobat_sl.exe for Acrobat and reader_sl.exe for Adobe Reader solved my problem. I then created a batch file that auto ran everyday and killed these tasks.


I know I'm late on this thread, but none of the things above helped me out, but I did find a solution to the proposed problem. Since my Adobe would not launch from the desktop, or the .exe in program files, I found a known good computer with the same Adobe and copied the Adobe files from that computer and replaced it with the broken PC adobe files. Adobe works great now.

  • This does not answer the question, please don't post your own questions, as an answer to a question. Don't worry the proper thing will happen to this answer, it will be deleted, allowing you a chance to install the patch that fixes this problem – Ramhound Jun 4 '16 at 0:02
