Missing x86 assembly or x86 assembly not registered

To identify assembly file and location, go to registry editor (regedit) and under HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\, search for the CLSID displayed in the error message. When you find the CLSID, open up the folder and click on InprocServer32 to see thepath to the file, the assembly name and class (See attachment).

Now that you know the name of the assembly, verify that the assmbly has been registered in C:\Windows\Assembly (See attachment second screenshot).

Also verify that the Program Files (x86) folder holding the Binn directory is present and that it contains the dll (See attachment, third screenshot).

If dll is present, you will need to re-register it again according tohttps://support.quest.com/SUPPORT/index?page=solution&id=SOL57534. If missing, you need to install/reinstall sql server client components.
