Hi peloflex,

Sorry for the trouble these Driver Signing issues are very difficult.

I didn't really want you to use Test Version 4.34a but rather use the drivers within that installed directory. In other words use Windows Device Manager then select Update Driver, then navigate to the c:\KMotion434a\USB Drivers directory.

Did you do this? If so what happened exactly?

There is always the workaround to do the re-boot-F8 disable driver signing enforcement to get the drivers loaded.

Regards
