how to declare teststand engine in visual studio 2008

[Shadad]

Hello

I'm triying to declare the teststand Engine.

This is the code.

Public

Class Form1

Public ts As New NationalInstruments.TestStand.Interop.API.Engine

PrivateSub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load

EndSub

End

and I get ...

'An error occurred creating the form. See Exception.InnerException for details.  The error is: Retrieving the COM class factory for component with CLSID {B2794EF6-C0B6-11D0-939C-0020AF68E893} failed due to the following error: 80040154.'

does anybody know how to initialize teststand API.Engine in visual studio 2008?

Thanks

This error can happen in .NET projects if you have the platform set to "Any CPU" (which is the default) and you are trying to run on a 64-bit OS. You need to create an x86 platform configuration for your project and build that.

Hope this helps,
