Cannot install drivers

[frankenkj]

Win 10 x64 machine -

Laser Grbl installed and launches fine - when installing driver CH340 driver, it extracts and finds the inf, but errors out when installing.
any ideas why ?

You can try this version if you want. Just extract it and run it outside of LaserGRBL.
CH341SER.ZIP

Have you been in to windows Device manager to see if there is one already there, and a comport number.

Maybe you need administrator privilege?
Try right-click, run as administrator

I tried that and same result.

Interestingly tho, without the dirvers installed I can control the laser via Laser GRBL and Lightburn. Maybe it's a non-issue ?

Maybe you have already installed them. Or you don't need them.

CH340 driver is needed only if your board use a ch340 chip for usb serial communication.
Different board types can use different chip.
