Trying to install GQ-4X to my Windows 8.1 laptop. When I try to install USB 2 device driver, I get this error message: Third Party INF does not contain signature information.
If I install setup from disc, the programmer is not found.
The message “Third party INF does not contain digital signature” is a warring. If you are installing software on Windows 8, then you need to disable the signature enforcement when the Windows starting.
