Hello, i have Windows Messenger 4.7.2009, and WLM 8.5
8.5 works perfectly but in WM 4.7 i cant login, it says me this error:
The WM version:
Help me, i patched the application but i cant log in
(I activated the āOld MSN supportā option before you ask for it)
OS info, in case someone asks:
I think itās because you have to use MSN Messenger 4.7, not Windows.
But Iām not sure.
The app name is āWindows Messengerā
In that case, did you click on the checkbox that allows you to use MSN Messenger versions 1.0-4.7 (MD5-based auth)?
If not, then Iād say create a new account with that option enabled. 
I sayed in the question ā(I activated the āOld MSN supportā option before you ask for it)ā
Whoops. Bad judgement. 
In that case, youāre better off using MSN 4.6 or lower. If my memory serves me correct, Windows Messenger 4.7.2009 uses the Tweener method of authentication, and I guess something goofs up when that happens. Since I am sure that MSN 4.6 and below use MD5 authentication, it has much more of a chance of working properly.
Hereās the ZIP file with the MSN 4.6 installer: mmssetup.zip (922.7 KB)
Just uninstall Windows Messenger, install MSN Messenger 4.6, patch is as necessary, and give it a go. Iād like to see the results. 
It worked!
Thank you!
PS: Do you have a Spanish version?
Since I got my version from a Wayback Machine archive, Iāll have to do some extra digging for that language-specific version. Other than that, thanks. 
While I couldnāt find the Spanish installers on the Wayback Machine, I was lucky enough to find them in @enhanoxās MSN client archive (MSN Messenger Clients : Microsoft : Free Download, Borrow, and Streaming : Internet Archive). I have packaged both the Spanish and Portuguese versions of the MSN 4.6 installers in a ZIP file for ease.

Enjoy.
