Patch Manager installation error: The Specified Account Already Exists

Updated January 4, 2018


The following error is displayed when running the Patch Manager installer:

The Specified Account Already Exists

The error occurs during an MSI installation of a Microsoft component, typically with the common language runtime (CLR) included with the installer.



All Patch Manager versions


  • Registry issue
  • Issue with updating the installation


  1. Identify the component with the issue from the point where the installer failed. In the example above, the installer is failing on 2012 x64 CLR types.
  2. Uninstall the CLR types.
  3. Run the installer again by right-clicking and running as administrator.
  4. During installation, the CLR types will be reinstalled and the installation should complete.


There are multiple components where this may fail. CLR types are the most common component showing the issue.
