You cannot use Microsoft Office Interop without Office installed - it is flatout impossible. Moreover: You are in an server environment, running Office is not recommended by Microsoft because there are lots of threading issues and sometimes a messagebox from Office will hang your thread.

You have two choices: - use the Office Open XML Sdk to compare the documents, but this is a lot of work because it is very different from Interop. There is the free book "Open XML Explained" which could help to get you started. - Use a library which capsules the Office Open XMl SDK - I never used the libraries for word, so I cannot give you an advice.
