Adobe has recently released an update that looks to have caused issues with 2008 R2 servers.

Adobe Reader version 2017.009.20044 is causing problems for Adobe Acrobat Reader DC upon launch.

After installing this update, you may see the following error:

‘Adobe RdrCEF has stopped working’. The ‘APPCRASH’ application name is ‘RdrCEF.exe’.

To resolve this problem, simply navigate to the following location:

C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroCEF

Once there, you then need to move/delete the following ‘exe’ files:

  • RdrCEF.exe
  • RdrServicesUpdater.exe

Once these files are either moved to another location or removed, you should now be able to open Adobe Reader with no issues!

  1. Brill! Thanks for the quick fix on our Terminal server. Does RdrCEF.exe do anything important? Are we going to miss it?

    1. Hi David,

      According to our team RdrCEF.exe simply handles cloud connectivity features. If you’re not using any cloud features, you won’t miss the utility.

      Hope this helps!

    1. Hi there,

      The version has been updated a few times since the blog was published so may not be applicable to the version you’re on.

  2. After installing Adobe Acrobat Reader DC 18.011.20040 application, when we launch the shortcut we may see the following error:
