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: 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.

Where should I look in Event Viewer? – irule311 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. – irule311 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. – Sami Laine 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 at 0:02
