Unable to install ClearContext

Hello
I am running Windows 8.1 and Outlook 2013 (64-bit).
I run the CC Setup program and this appears to proceed correctly. An entry in Control Panel -> Programs is created. However, the CC Add-In does not load. I have tried:
* FILE -> Slow and Disabled Add-Ins. The CC Add-In is not listed
* Disabling all other Outlook Add-Ins and reinstalling
* Disabling Avast AV and reinstalling
* Creating a new Outlook profile with a new PST file and reinstalling
* All of the above with a complete Uninstall and Reinstall
I have tried FILE -> Options -> Add-Ins -> COM Add-Ins (GO) and re-enabling the Add-In, however this fails too. One oddity, which you will see from the screen shot. When I select the CC Add-In, Outlook does not show a location. All the other Add-Ins show a valid filename.
Any suggestions as to how to get ClearContext installed?
Thank you
