Windows 7 unable to connect to RFID mobile reader

Hello,

 

We are trying to connect our MC9190-Z and MC3190-Z RFID handlheld readers (Windows CE) using their USB cradle, but we get an error message indicating the driver couldn't be installed. In 4 of our Laptop/PC's but it only works in 1 of them. The OS is Windows 7 64 bit in all of them.

Is there any device driver available that is not the one from windows update? Is there any different solution?

Thanks
