DLL Hell?
-
I wrote an app using some active-x com dlls in C#.NET The app works fine on my computer where I wrote it but when I install it on an other computer I recieve the following error:
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in TestApp.exe Additional information: Retrieving the COM class factory for component with CLSID {8B71E7FF-699F-4610-9379-DE3A92D519BD} failed due to the following error: 80040154.I've included all the dlls I use but still receive this error on the other machine. Do you have an idea why? regardsRadgar "Imagination is more important than knowledge." - Albert Einstein

My guess would be even through the dll's are on the PC they haven't been registered. I think you need to run the regsvr32.exe on those dlls. That's my best guess. Hope that helps. Ben

Thanks Ben but that's definitely not the problem.

Well, that's what error 80040154 says is the problem. It basically means "Class not found", whether that's in reference to a direct call by your code, or one of your .DLL's has a dependancy on another DLL that's not registered properly. It's possible that the COM Servers you registered have to be restarted.
