Thanks for reaching out to Xencelabs. I have not seen the Setting program not open on the Windows platform before?
I would like to have you reach out to support.zencelabs.com and open a ticket with Xencelabs Customer Care.
Please include the version of Windows 10 you are using (send then the System Infomation screenshot) and if you are using a VPN and any System or Internet Security software.
If you would also start your Windows computer in Safe Mode and see if you can access the Setting program that way, that would be helpful.
Good of you to reply, I am sorry I left this, I actually went on a surprise holiday. There was a ticket already open at the time of my posting the above.
However, pre getting a reply from the ticket, Carson did some troubleshooting with me over email correspondence. It occurred to me (from problems with things in the past) to eventually mention that I run 6 monitors. Quick Keys only works with 4 or less monitors attached.
IF ONLY I had of led with that. I really hope they get the driver issue rectified soon.
Again, thank you for taking the time to reply, Mike.
