Make sure you place the loader in the same directory as the msnmsgr.exe and then run the loader twice to open up two MSN Messenger clients.

It works, if it didn't then everything about it would fail, not just polygamy.

Edit: This loader modifies msnmsgr.exe in memory, hence why it's called a loader. As stated above to run 2 sessions of MSN Messenger you have to execute the loader twice. I hope that was clear

Edit 2: Thanks Dash
