Adobe Reader XI will not launch

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!

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.

Just had this happen on two Windows 7 Machines just after an Adobe Reader update a few days ago.

The solution for me was:

• Right click the AR shortcut
• Click Properties and then the Compatibility tab
• In the Compatibility mode section, select Run this program in compatibility mode for
• Choose the Windows version you're on.
• Click on Apply and then Ok

As a workaround try Adobe Reader and Acrobat Cleaner Tool

Description:

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.
