Default COM Interop Error on 64bit ?


I have create a COM class in VB.Net VS 2005, which works and runs fine for use in classic asp.
Tested it with IIS5 and IIS 6 : No problem

Now when installing it (using same setup project through VS) on a X64 machine it fails.

Caling it from a classic asp page :
ActiveX component can't create object

Calling it from .net gives :
Retrieving the COM class factory for component with CLSID {B6AA7C90-FF32-4353-8537-89A872E298D1} failed due to the following error: 80040154.

Is it not registered correctly ? I hought the setup would do this ?
Is there another problem ?

Thanks for any help

I'm having a similar problem. I have discovered my issue involves using an ASP page. My code works fine in an ASPX page when I can give <%@ Import Namespace="CFW.Barcode" %> directive.

I need it to work in ASP. I've tried regasm and putting my assembly in the global assembly cache but neither for for ASP. I was thinking it might be related to trying to run a 32bit app in IIS in 64bit mode as my program works when I set IIS for 32bit mode.

Have you figured something out?
