Having trouble with ASCOM driver 64 installation

Hi All,
I'm trying to get my Aluma CCD694 to work with TheSkyX under ASCOM. I can get it to work under the 32bit version, but that's being phased out, so I have to get this moving along.

Anyway, when selecting the DL Imaging Camera 1, then I hit properties and get the following error.

Please help me to manually install the driver. There's no unknown USB device in Device Manager.

The camera shows up under DL Config Utility.

I'm a bit of a Windows numpty, so please take it easy on me...

Cheers
Stu
