[VB CS4] CreateObject with Photoshop 64 bit possible?

Question

Hi,
I wrote a VB6 application for a customer some years ago, which is using Photoshop for some imaging stuff.
The thing is that the customer has now installed the 64 bit version of Photoshop CS4, and she gets the well known error nr 429, ActiveX component can't create object, trying to run the program.
The error is most likely to ocurr on the line trying to initiate Photoshop:
Set appRef = CreateObject("Photoshop.Application")
The appRef object variable is declared as this:
Private appRef As Photoshop.Application
And in References for the project, I'm pointing towards the "Adobe Photoshop CS4 Object Library".
Is there another name for creating the application for the 64 bit version, using late binding in the same manner as for the 32 bit version?
Best regards,
Andreas

Hi!
Sorry for not answering sooner!
Well, it seems I had to rewrite the application in Visual Studio C#.
(Looking in the code) I used this declaration for the application object (Photoshop):
private dynamic appRef;
and this code to set it to an instance of Photoshop:
appRef = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.Application"));
Documents are opened like this:
docRef = appRef.Open(FullFilePath, null, null);
Best regards,
