Dynamics CRM Roll up installation fails: The upgrade cannot be installed because the program may be missing or may update a different version. RRS feed

  • Question

  • Currently we're running a Dynamics CRM 2011 RU13 Environment which we want to upgrade to RU17 currently. (We're considering RU18) Only when running the installer it fails to upgrade CRM.

    The error which appears is: "The upgrade cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade."

    In the log files we can see, that it tries to repair the installation (UR14MspUninstallAction -> RepairMsiFeatureSetToAdvertise) for a still unknown reason. When it tries to repair, it also asks for the Server.msi. We entered the original installation location for CRM 2011 (which can also be used to repair the installation). We also tried using the RU14 installer, but the same message appears.

    Has any one any ideas for further debugging options?
