Solution 1

There is no class registered on that machine with that CLSID. I think you simply forgot to install the software that came with the device. Often you can install additional software that is included on the driver disk, which also includes components and classes for controlling the device using custom software. Maybe it even got a redistributable package of it. Check it out.

Good luck!

Good explanation. I'll also add a result of quick Googling by CLSID: they mention Fingerprint SDK and a license in this topic, OP could check it out
