Don't remove Windows Messenger. Or install v5.1 after the fact. Build 701 is the latest I think. If you look, you'll see that when you try to use it in Windows LIVE Messenger and it says you need the latest version but you check and you are "in fact" using the latest verion of WLM. Click the link that it provides and see where it takes you...the download page for the old school Windows Messenger. I'm gonna try to make a MsMsgs removal for RVM Integrator that doesn't break remote assistance...but that is not exactly high on the totem pole if you get my drift.
