UC100 USB Driver issue driver not loading

[SRHEAUME]

Hi,
I have been successfully using UCCNC for many years both with UC100 and UC300ETH.
Yesterday I was using UC100 without problems.
This morning, for no reason UCCNC with UC100 could not validate my license.
However UCCNC with UC300ETH was working OK.
My troubleshooting:
- Checked the valid license key file => UC100 License File is in UCCNC folder as usual
(along with the UC300ETH license file)
- Checked with UCxxx_utility scan => Ucxx device was not found
(but UC300ETH thru internet cable has license found)
Investigation of USB connection and driver
- Checked the UC100 device => Green LED ON, Blue LED ON
- Checked Device Manager under Universal Serial Bus Controller => NO UC100 device listed
- Reinstalled USB device driver => Report installation successful Message:
IPSES S.r.l. IPSES CDM Driver Package - Bus/D2XX Driver (01/27/2014 2.10.00) Ready to use
IPSES S.r.l. IPSES CDM Driver Package - VCP Driver (01/27/2014 2.10.00) Ready to use
- Changed the USB Cable => No effect
- Windows doesn't beep when I plug the USB Cable meaning that it doesn’t load a driver

- Did a complete reinstall of UCCNC => Same problem

Don’t know what else to try considering it has been working well for years.
No change were made to the Laptop since yesterday unless there was a hidden Win11 updates done during the night…

Can you help ?

My System
Recent Laptop Dell G16 7630 with 32.0 GB, Win11 Home edition 64 bits all updates applied
UCCNC version: 1.2113

Hi,

Please try this:

Also make sure to enable the .NET framework 3.5 in the Windows features.

I tried the link http://www.szentkereszty.net/uc100/ which is not valid anymore
Looked at a Youtube video "Replace UC100 Driver in Windows 10/11" ( https://www.youtube.com/watch?v=WhzE9bwHOsk&t=1s )
which also point at the invalid szentkereszty web site
Where else could I find this driver for 1.2113 ?
