using interop assemblies for excel in c# application

Question

I was wondering about the following Scenario: I developed a C# application, that generates Excel reports based on the Microsoft.Office.Interop.Excel Assemblies and installed the application on a Windows 2003 Server without installed Excel, but I don't get it to work there.

So basicly: Do I Need Office on the machine, where I want to use the above named assemblies or might it be for other reasons?

Thanks in advance for all well meant answers.

Answer 1

Yes, you need to have Excel installed on your server. Also, there are special licensing requirements for this, so please see:
