gijs_liegbeest, i've attached a .reg file that I use to add 3 of the 4 MSN typelibraries to the reference list.
Works fine for me.
I'm working on this same type of thing in C++, but i'm still debugging that
P.S. the easiest way to use them is to change the arguments from oMessenger as Object to oMessenger as IMessenger, etc. etc.
--EDIT--
.reg files can't be uploaded, so i've copied and pasted the contents of the .reg file below this section
