Nice , i made a thread about it too !
You can also use 8.5
the sound works in 7.5 ?
if it doesnt u can make it work by converting them to wav files its working with 8.5 
If you install more windows libraries then sounds should works. I put the commands soon
winetricks tahoma then hit enter
winetricks riched30 then hit enter
winetricks msxml3 then hit enter
winetricks msls3 then hit enter
Yeah thats from my thread
sound should work by converting them to wav its working just fine with me
Yeah, but Ive removed that once and I cant install back because the installer doesnt install the WLM lol
wdym
Ive installed the WLM 8.5 firstly. I removed that for make the video. And now I cant install back the WLM 8.5 because installer doesnt appear and doesnt do anything. But MSN 7.5 is works.
Oh i had the same prob type in the terminal wine uninstaller and see if there is wlm 8.5 if so uninstall it and if it still doesnt work try uninstalling wine and reinstalling it
Yeah, now works. Thanks 
You’re welcome
sound working?
On it to make workable
i have the preconverted files here https://drive.google.com/file/d/1vQtCox9uqnxkNgqKE1b_KD0v_xupbFYU/view?usp=sharing
replace the old ones with these ones
after open wlm and go to tools>options>alerts and sounds and select each alert and click browse and then choose the converted files that you replaced and do the same for all the alerts and if you still didnt replace them then go to the home directory and right click and click “show hidden files” and go to .wine>drive_c>program files (86)>windows live>messenger and paste the modified files in there and it will ask you to if you want to skip or replace the files because its a duplicate click replace and then follow the previous step to set msn to use the modified files
