I have the same situation I think, I tried to install the driver for my DSO-2090 oscilloscope with no a success, it says:
Windows cannot verify the 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)
