Error 1911. Could not register type library for [file path\file] - when installing or upgrading

When performing a new installation or upgrade of your Blackbaud product, you may receive the following error:
  • Error 1911.  Could not register type library for [file path\file] could not be registered.  Contact your support personnel.
In July 2015, Microsoft released KB 3072630, which corrected security vulnerabilities in the Windows Installer service. This service is used by Blackbaud products when installing on Windows operating systems.   This Microsoft Security update may affect new installations/upgrades of Blackbaud products on Windows servers and workstations when the Terminal Services/Remote Desktop Services role is installed or enabled.

In order to resolve the issue you are experiencing, please complete the following steps in the order listed below:
  1. Uninstall Microsoft Security Update KB's 3072630 & 3139923.
  2. Restart the computer.
  3. Install the Blackbaud product.
  4. Perform a Windows update to re-apply Microsoft KB 3072630 and Microsoft KB 3139923, if desired.
Please contact the appropriate software vendor or IT professional for assistance with this process or issue, which is beyond Blackbaud's scope of support.

This problem does not occur when the installers are run under the SYSTEM account. As a result any existing installations of your Blackbaud software are not affected by the issue as installers are launched under the SYSTEM account.
