After configuring the HP ALM Service and attempting to start the TDoD service, I am receiving the following error message:


FATAL - Exception occurred while starting service: Retrieving the COM class factory for component with CLSID {C5CBD7B2-490C-45F5-8C40-B8C3D108E6D7} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

This error message means that you have not yet installed the HP Quality Center Connectivity tool. 



You will need to install the HP Quality Center Connectivity tool. Here are directions on how to do this:

  1. Open HP ALM in a web browser.
  2. Click the 'Tools' tab or the 'Add-Ins' page.

  5. Save the add-in file as TDConnect.exe.
  6. Run TDConnect.exe to install it.
