Hi All,

I have written a WCF Service (.net 4.0) that has a reference to the Microsoft.Office.Interop.Excel.dll.

I just happen to have Office on my machine. I know all the arguments as to why office should not be used server side, but with this app there really is no choice in using the interop. That said, I do not need to use Excel application just the interop services. However On my machine I had to use the DCOM Configurator to ensure correct permissions for office. On the deployment box we do not have office installed, but because I've made a reference to the interop dll, I assume that this should be installed by the installer. will this be enough on the server for my app to use the bits it needs from Excel or does the server still need full blown excel installed?
