Visual Studio 2005 Professional Edition:
My app runs fine on my development computer, but, bombs out on the 3 other computers that I installed it on (all 3 were running Windows XP Pro). It installs OK, but, upon execution, it immediately aborts with a System.InvalidOperationException.

I inserted a MsgBox(" " command at the very beginning of the Form1_Load Subroutine, so I know that the program itself never executes.

The installs were all from CD.

Are you sure that Net Framework 2.0 is on the other computers? That is the only thing I can think of that could go wrong.

Yes, it was downloaded and installed as a prerequisite.

I suspect that this could be my problem:

My.Computer.Audio.Play("C:\Documents and Settings\Owner\My Documents\Visual Studio 2005\Projects\OrthoLabRx\OrthoLabRx\Resources\PodVwBy.wav")

I placed the .wav file in Resources, but, I can't seem to access it from there.
This does not work:
It says "value of type 'System.IO.UnmangedMemoryStream' cannot be converted to 'String'.

Try this:
My.Computer.Audio.Play(My.Resources.PodVwBy, AudioPlayMode.Background)

That frequently went PFFFFFFFT instead of CLICK.

But, this did the trick!

My.Computer.Audio.Play(My.Resources.PodVwBy, AudioPlayMode.WaitToComplete)

I also have the same problem so can someone help???
The same error which is : event type clr20r3
P9 :system.inavalidoperationexception

Did you ever find the solution to the problem? I'm having the same problem and can't find a solution.
