OPC Ua COM Proxy Server problems|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

Hi,

I have this old version of OPC Ua ComProxyServer with an old OPC stack (1.2.334.6) that I use towards my new OPC UA Server, which is 1.03.341.0. And that works fine. 

But I tried to update the Proxy Server to the latest one (from same .NET package as I use for my OPC UA server). But then I get a strange error message. When I connect with MatrikonOPC Explorer, it says connected: Yes, State: Failed, 

In OPC Security Analyzer everything is green until AddGroup returns error 0x80004005 Unspecified error.

I have tried to /install /uninstall /regserver /unregserver with the Proxy exe file, I also tried to create new configs with Configuration Tool, but same error. When I switch back to the old version it starts to work again, so I guess its not DCOM related since the old one works perfectly.

Any help would be appreciated 🙂
