what is System.Runtime.InteropServices.COMException (Exception from HRESULT: 0x80040111 (CLASS_E_CLASSNOTAVAILABLE))

When running PreScan(R) on window 7, matlab 2017a environment. This problem suddenly showed up. It is not clear to me whether I shall reinstall the PreScan SW to fix it or take other actions.

I did some research and find out that there is a comexception 0x80040154

Then checking the register, however, I did see class DC1C5A9C-E88A-4DDE-A5A1-60F82A20AEF7 under HKEY_CLASSES_ROOT\CLSID. So I'm not sure this is the way to go.

Any suggestion is highly appreciated.
