Unable to open OPC UA Configuration Manager

Currently using KepServerEx V6 (V6.14.263.0) and unable to open the OPC UA Configuration Manager utility. This is making it difficult to trust new certificates.

No errors, icon shows in task bar but nothing opens and task manager shows the app as not responding.

Greetings @AF_14035066,

 

Thanks for your confirmation.

Could you please confirm which application shows in the task manager? 

 

I think we need to dig into this issue further. I recommend opening a support ticket with the Kepware Technical Support team for a more in-depth investigation.
