COM Interop Nightmare

I am using WebBrowser component in a Windows.Forms application.
When trying to run the application on a machine that
has no VS.NET installed, only the .NET framework (and SDK),
an unhandled exception is thrown before the main() function.

[thread 0x10c] Unhandled exception generated: (0x04a73da4)
<System.NullReferenceException>
_className=<null>
_exceptionMethod=<null>
_exceptionMethodString=<null>
_message=(0x04a75bb8) "Object reference not set to an instance of an
object."
_innerException=<null>
_helpURL=<null>
_stackTrace=(0x04a75c34) array with dims=[36]
_stackTraceString=<null>
_remoteStackTraceString=<null>
_remoteStackIndex=0x00000000
_HResult=0x80004003
_source=<null>
_xptrs=0x0012f18c
_xcode=0xc0000005

The referenced assemblies have been included, I monitored the registry all
the needed components where found. I still have no idea, what to do next
to fix the problem. Maybe using another debugger like windbg.exe will show
more?

Thanks

Has the target machine got the same version of IE

i.e. the same Shdocvw componen
If you embed the AxWebBrowser component in a form, then you are embedding this specific version of IE, hence wil
not work on another machine with another version

This is how I understand it anyway
You need a method of loading the Ax dynamically, so you get whatever versoin is installed.

Thanks, that was the problem. I will not dynamically load the browser
component, call me lazy. But I will rather update requirements, to use the
supported version of the browser.

Thanks again
