thing is, it would be extremely difficult to do.
but i guess it is possible.
goto C:\Program Files\Msn Messenger
and create 3 folders and rename them for each language. Now copy msnmsgr.exe + all other files into all three of the folders.
Now copy msgslang.dll into the folder with the name of the language you are currently using.
Now, you need to download the right language of messenger you want. Install messenger, then again copy the msgslang.dll from the newely installed messenger to the folder of the same language.
Repeat the third time.
Now using polygamy (

bit complicated. but it should work
