It has always been possible to install two versions of Messenger. That hasn't changed now.

Hi, is it possible to install and have *both* instances of WLM 2009 and 2011 on a PC? Or is there no way to avoid 2011 replacing version 2009 when installing?
Sure...
You first need to install the lower version (in this case WLM 2009). After that you make a copy of the complete installation directoy and all its subdirectories (and make sure you copy everything, including hidden files etc if any).
Then you install the later version (in this case WLM 2011), so the previous (old) version gets 'updated' in its original installation directory.
From now on you can use the new version (from the original installation directory) and the old version (from the copied directory).
But note that this method is not officially supported and it could lead to some troubles. And also note that in order to update the oldest version (eg: a new build of WLM 2009) you first need to completely uninstall the newer version (WLM 2011) first and then repeat the whole process again like described above.
