USB driver digital signature problem with Windows 11

[aportell]

Hi, can some one please help, I have been trying to get this to work with shopwexpress V9. in windows 11 because I have updated my computer. Do you know what the tricks are to make it work?It tells me the driver is not digitally assigned. Has any one had success with making it work?

The USB drivers of all our DMX interfaces have the same digital signature, and for an unknown reason Windows11 does not accept the signature of the interface Cable only, while there is no problem with the other DMX interfaces.
Not easy to fix that problem ; this will take time to understand what Windows 11 does not like only on that interface.

In the meantime, we do not see any other way than to still use Windows 10.

Sorry for that.

Can you please tell me what is the next on up from the express 100 that will work with showexpress?

The next on up from the xpress100 is xpress512S.

It works well with ShowXpress and Windows 11.

Thanks for that. After doing multiple testing on windows 10 & 11 newer laptops, I finally got it working in windows 11 this also appplies to the newe laptops in windows 10. Hopefully this might help others.
Installed Showexpress 9.4.3 on Windows 11 Version 25H2

If you disable driver signature enforcement. By running a command prompt as admin.
Cmd <Enter>
Bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS
Restart and then try to install the DMX to USB Driver in Device Manager.
I used 2017_07 and it installed it correctly.

NB: If you still have issues you may need to disable Secure Boot in the Bios
One other thing i did was disable bitlocker as well.
That’s it all lights, smoke machines & moving heads functioning correctly.
