i recently upgraded to 7.40 (from 7 3.7) on my windows 11 machine and since doing so my GX4x4 is noch recognized anymore. In the device manager it now pops up as "IntraOral USB 1.5", uninstalling the device (including drivers) and re-install doe not help.
Has anyone here still a copy of the 7.37 version? Unfortunately it's no longer on the website for download. Would like to try if this version fixes the issue.
I figured some of it out.. Windows did an update and put a bad device driver configuration out.. It has a bad line with the device ID that just happens to match the programmer
There is likely an easier way.. but I downloaded a utility called usbdeview In that you can right click and find the OEM#.inf file name The use the command (and a admin window) pnputil /delete-driver oem<#> .inf /uninstall /force and delete the INF files (there were 2 devices that popped in.. I deleted both) Then I reinstalled 7.40. and it worked..
It is actually a Microsoft mess up as far as I can tell.
Looking for GQ-4x4 7.37 Software Version
