Help!!

My dev team have all gone on holiday and I've managed to screw up our K2 project. For some reason despite Interop.Office.dll appearing as a reference in the project when I compile I get the following error:

Metadata file 'Interop.Office.dll' could not be found

I am trying to compile in K2 studio on a development machine that opens the solution from our K2 server. I have installed .net 1.1 sdk and the office programability support but for some reason I cannot find 'Interop.Office.dll' in the references nor can I find Microsoft.office.core or Microsoft office 11 object library. How can I install this assembly so I can add it to my project?

Any help really appreciated!
