Client error messages on Windows 7 64bit

<p>Hi,<br />
I'm testing the client on a Windows 7 64bit system. The client shows the available usb devices but when I try to use a device and install the drivers, as requested, I receive the following error messages,<br />
The System Messages window shows the following messages
