While playing about with Microsoft Windows 2003, I needed to install an MSN client, which at the time was Windows Live Messenger 2009.
Now Microsoft in their wisdom has for some reason stopped WLM 2009 from installing easily onto any of their servers OS’s i.e. Windows Server 2003 from their normal downloads.
There was numerous guides on how to “bypass” their checks, non of which worked.
After some digging around, I found the .msi separate installers packaged in the distributable installer. These msi’s install silently and more importantly, don’t check the OS version. These msi’s will allow you to install WLM onto any computer and they should also help roll it out over a network.
If all you require is messenger, all you need to install from it is ‘Contacts‘,’wllogin‘,’Messenger‘ and ‘dw20shared‘.
