Acrobat Error 28000


When I try and open Adobe Acrobat I get an error message that states the following: 

Error 28000: Installation of Acrobat Licensing Module has failed.


  • Windows 10
    • Adobe Acrobat


It is possible that the installation of the Adobe software or an update of the Adobe software did not complete fully or successfully. Upon launching the program the installer may come up and present the above error message, and then crash the program. 


  1. Go to the following location: C:\Program Files (x86)\Common Files\Adobe​​​​.
  2. Rename the OOBE folder to OOBE_old.
    Note: You may receive a prompt asking for permission to make this change. It is OK to allow this change to be made.
  3. Attempt to open the Adobe Pro Application and wait for the installer to complete.
  4. If the above steps do not work, please remove and reinstall the Adobe Acrobat Pro application from your computer.

Please contact the ITS Service Desk should you continue to experience problems with the software.
