Calling c# assembly - Works from Excel 2003, not from XP

Hello

I have a c# assembly that Iam calling from Excel 2003 VBA. The assembly has 4 dependencies (located in the same folder). All have strong names. I use regasm etc etc.

I can call the class/functions in the assembly from Excel 2003, but the code does not work from Excel/Office XP. The error message is : CDCOM.dll or one of its dependencies could be found.

Any help is very much appreciated.

thank you.
