Running Windows 10 and Rumba Desktop 9.5 SP1. I'm trying to configure CEL to connect to z/OS TN3270. I've built the necessary signon script and customized it for CEL. When I go to the TN3270 Mainframe Securities Properties window and select Client Certificate I get a popup that says No certificate available:

I have a client certificate stored in the personal certificate store in Windows. I'm not sure what is preventing Rumba from finding it. Does anyone have any suggestions on what I should look at?

Hi,
I tested with Rumba 9.5 SP1 on windows 10 and it works fine for me. Rumba picks up my personal cert from the certificate store.
I added a second certificate to my personal cert store and I now can choose the certificate .
When I delete the certificate then I receive the same message "No certificate available".

Not sure if you have a problem with permissions or  an issue with the certificate.

Can try and trace the WDDspPag.exe with the sysinternals process monitor(procmon) when it tries to retrieve the Certificate ?
You can find the tool under https://live.sysinternals.com/

See below my log:
The long number (red square) is the thumbprint of my certificate.

What do you see in your trace ?

Thanks @ndre. It took a while to work through the information you provided. Knowing that it worked for you helped...

The main obstacle was we are not allowed to add any unauthorized software so I couldn't use the tool you recommended. I also only have limited admin rights on the workstation.

The bottom line is that when they built the workstation they loaded the server/client certificate in the Local Computer Personal Certificate store. Rumba was unable to find it there. In MMC I exported this certificate and imported it into the Current User Personal Certificate store and Rumba was able to find it. The workstation team is going to look into this.
