DWUpdateServiceLib.IAgentEx4 failed
Hi,
Some users get the error message: 'QueryInterface for interface DWUpdateServiceLib.IAgentx4 failed.'
This is the message from the an exception thrown in C# while AppUpdate() method is called to invoke a check for updates. Anyone knows what it means :confused: ?
Thanks in advance.

It may be possible that the Update Service binary was not registered properly on the system. Can you try running the following on the system with the problem:
Also, this is my sample C# code that I used to invoke a check for updates:
C:\program files\common files\installshield\updateservice\agent.exe /regserver
Also, this is my sample C# code that I used to invoke a check for updates:
DWUpdateServiceLib.IAgentEx4 agt = new DWUpdateServiceLib.AgentClass();
agt.AppUpdate("{AAAAAAAA-AAAA-AAAA-AAAA-AAAAAAAAAAAA}", DWUpdateServiceLib.RunType.AppMenu);
agt.AppUpdate("{AAAAAAAA-AAAA-AAAA-AAAA-AAAAAAAAAAAA}", DWUpdateServiceLib.RunType.AppMenu);
