create object function failing in iis7

I have an Application developed in visual studio. The Applicaton uses the create object function to activate an Application. The function was perfectly working in windows 2003 server.
when the application was migrated to windows 2008 server with iis7, The Create object function is not working. The function works fine in visual studio IDE environment, but fails when hosted in IIS7.

kindly advice.

Best regards

Can you post a little more detail about the error you are getting?

- What object are you instantiating?
- What action is taken when the error is received?
- What is the error message?

Dim Baanobj=CreateObject(Baan.Application)- My error is getting generated from this Line.
The error message is cannot create Acivex component.
Dan McFaddenSystems EngineerCommented:
Are there any error or warning messages in the Application Event log?

Can you post the complete event log message?

Also, I would check the permissions on the ActiveX DLL file to see if the web application's App Pool identify has at least READ permissions on the file.

Dan McFaddenSystems EngineerCommented:
Also, what version of the Baan activeX object is this?  The version may be incompatible with Server 2008 and IIS 7.

Is it correct to assume you are writing VB.NET?
