No com port, security error?

[PE0SSB]

Hi folks. I am new to this forum and discovered a lot of information here. Great!
I tried to reprogramm my GD77, wit OpenGD77 installed and use OpenGD77 CPS. Worked fine until nov 2023. Today March 27 2024 i can't come further due to com port error. CPS shows the error message "No com port .......". I run win10/64. In the win devicelist I discover OpenGD77 (com3) with a security? sign. Despite of this error i could upgrade my GD77 with latest firmware 2024 and PC with latest CPS, but without any change and still can't read and programm the radio. I wonder if someone can point me in the right direction to solve my programming issue with this wonderfull radio. Thanks in advance, Henk, PE0SSB.

I did Roger,
Meanwhile I installed the CPS on another -same model- laptop, also with Win10/64, and here all worked fine!
So this error is specific related to this PC and I don't know how to resolve. I have to check what app's I installed last months to see if one can interfere with the com port handling or so.
Meanwhile I can use this second PC to programm, what works for the time.

Thanks for thinking with me.

Ok.

I have one PC where the STM DFU driver crashes to Blue Screen Of Death, but I never saw the problem you experienced
