USB to CAN v2 driver install failed on windows 7

Hello,

The installation of the driver of my USB to CAN v2 interface has failed on my windows 7 PC.
I was working and I installed the Ixxat VCI 4.0.925.0 driver and it does not work anymore.
In the peripheral manager I see my interface in the IXXAT VCI V4 interfaces group but noticed as unknown peripheral. When I try to update the driver windows is telling that the best driver is already installed.

Any idea of how to proceed ?

You may need to update the firmware on the USB-to-CAN if you are not on 1.07, see:

Thank you for your reply. It may be the answer. Actually I found and installed the previous driver VCI 4.0.482.0 and it works now.
