I agree but I cannot change my company policies from one day to the next. I had already noticed all the requirements you have mentioned but I already installed the driver on Windows XP without even forcing it, just decompressing the installer.
However, as you correctly said, I had to install .Net 4.0 client to be able to install the Showcase, but I can’t open the control panel to create my profile so I’m not able to test the device (with that drive installation I have made).
I was thinking of using your SDK to make a little test tool and if that works compiled to Windows XP I will then start developing to integrate our products with your device. If all that fails I don’t have a clue of how I can use your devices.
