Yes, the request is quite reasonable. Here is what you can do:

Instead of Office interop assemblies which require Office to be installed, you can use Open XML SDK:
http://www.microsoft.com/en-us/download/details.aspx?id=30425[^].

This way, you can support new XML-based Office formats (such as .DOCX, .XLSX), ECMA-376 standard:
http://en.wikipedia.org/wiki/Microsoft_Office_XML_formats[^],
http://en.wikipedia.org/wiki/Office_Open_XML[^].

This is another option: http://npoi.codeplex.com/[^].

Sorry, I don't know what did you do wrong. I know that we have the code for creating Excel document and exporting the data from our product, in the company where I work, and it works without any problems...
