I have VB.NET classes registered as COM objects (.dlls) which I am calling from a VFP 6.0 application.

When running within the VFP IDE all works fine.
However, when I try and call the .NET classes from our Enterprise application running through Windows XP (i.e. double clicking the EXE from Explorer) I get the following error:

OLE Error Code 0x8007000b: An attempt was made to load a program with an incorrect format.

Creating a simple prgram and comiling as a VFP exe and then running from Windows XP also works fine.

I then tried to create a .NET object as the first line in Main.prg of our Enterprise app but still got the same problem.

I have tried re-building and re-registering the dll but without success.

Any ideas out there what might causing this?

Thanks in advance,
Roger Smith.
