QueryInterface for IAgentEx failed

[CChong]

I’m trying to write a small application on C# for downloading and installation of our product.
My test application is working well on the development computer, but when I installing it on another one. I get an exception: “QueryInterface for interface DWUpdateServiceLib.IAgentEx failed”
Any ideas?

Have you included the Update Service in your install to the test machine?

Thanks for replay!

I guess that the message was because of wrong .NET runtime merging module.
At least after correcting it, the message has disappeared.
Now I’m getting Error 13001.
I guess it’s because the end-user computer somehow doesn’t know where my Notification server is.
Do you know how to set it using IS Developer 7.01?

Yes, I also started from it…
Unsuccessfully yet 😞
