I've got the very annoying problem that Adobe Reader XI simply will not open. I can view PDF files in the browser just fine, but PDF files on my computer will not open. The program simply will not launch.

I do not get an error. Nothing happens.

What I have tried to solve it myself:

  • Opening Adobe Reader XI on its own instead of clicking on a PDF file
  • Repairing the installation
  • Reinstalling
  • Executing as administrator (I have UAC disabled, so this should not matter a.f.a.i.k.)
  • Executing as Windows XP SP 3
  • Executing EULA.exe and accepting it

None of these seem to work.

Can anyone help me out? Thanks!

Have you checked the error log? –  Ramhound May 3 '13 at 18:13
Might sound silly, but what application is the pdf filetype associated to? –  M.Bennett May 3 '13 at 18:13
Ramhound - No, I have not. Where can I find the error log? –  JohnHeroHD May 3 '13 at 18:14
M.Bennet - Adobe Reader, but that should not be an issue, because opening the program by itself is not working either. –  JohnHeroHD May 3 '13 at 18:14
Check the Event log > windows.microsoft.com/en-us/windows7/open-event-viewer and give us the info given. –  M.Bennett May 3 '13 at 18:21

I use TuneUp Utilities on my system. That program appears to have blocked Adobe Reader from starting. Because after killing the TuneUp processes, Adobe Reader started just fine.

That is probably because Tuneup decided it was wise to delay the Adobe processes or something fancy to boost the performance of my system. But that part of the program is apparently a little bugged because the delay was indefinitely.

As a workaround try Adobe Reader and Acrobat Cleaner Tool


The Adobe Reader and Acrobat Cleaner Tool removes a standalone installation of Reader or Acrobat, including any preferences and settings that may be preserved during a standard program uninstall.

And then try reinstall of reader get the download.

i also use tuneup utilities but instead of disabling tuneup utilities and going through all those uninstalling processes i went to adobe reader icon, right click > properties > compatibility then changed the compatibility mode from windows 7 to windows xp sp2. downside is reader will prompt asking if you want to open your document without protection. which is fine for me.

I have same problem , solved by changing file extension from "C:\Program Files\Adobe\Reader 11.0\Reader\AcroRd32" to "C:\Program Files\Adobe\Reader 11.0\Reader\AcroRd32.exe" Then try to open .pdf files as "open with->browse->AcroRd32.exe" and that it!
