Invalid driver signature on windows 7 and 64bit
Hi, every one,
I have a trouble about USB driver signature. The picoscopes were installed on some windows 7 and 64bit PCs. Some picoscopes can work, but some picoscopes can't work because the driver have some problems. It displays the following information:
"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)"
Please give any help, thanks.
