Does the other pc have live messenger installed? If you added a COM reference to the messenger library then this library (and dependencies) is going to be required on any PC that your app is installed to.

Does the other PC have the same version of Live Messenger installed or a different version? The COM interop stuff can be very fussy about versions of software prior to .Net 4.

 

The interop.xxxxxxx.dll doesn't need to be registered on the target machine as it simply acts as a wrapper around the underlying COM component that should already be present and registered.
