I am also having problems using this NXP NTAG Plus Explorer Kit. I cant even get the reader to work due to windows 7 driver issues and have no idea how to solve them. I even went to the uTrust website and tried their installer / driver and got the same response.
"Windows encountered a problem installing the driver software for your device
Windows found driver software for your device but encountered an error while attempting to
uTrust 3?00 F CL Reader
Windows cannot verifythe digital signature for the drivers required for this device. A recent
hardware or software change might have installed a file that is signed incorrectly or damaged, or
that might be malicious software from an unknown source. (Code 52)
If you know the manufacturer of your device, you can visit its website and check the support
section for driver software."
Really? More Windows 7 64 bit driver issues that cant be solved?
I cant move anything to another PC or version of windows so if I cant get this fixed, I guess I will have to dump my plans to develop my solution that would result in millions of NXP Tag IC sales to some other vendor...
