qtVlm 5.12.2 not working on Raspberry Pi4

I tried to install qtVlm on Rasperry Pi4 Mod.B 64 bits. I tried it both on Raspbian and Debian OS. Each time I could not open qtVlm. I click on the exe file and nothing happens !?
Any idea to fix this problem ?
Thank you for your help
Regards

Hello,

Was it working before ? or is it a first install ?

Did you look in this thread: www.meltemus.com/index.php/en/forum/qtvl...ll-to-raspberry-pi-4

Don't hesite to post in above thread if you have further questions

Version 5.12.2 never worked. Perhaps I need to try an older one.

Ok. It is working in current version. Have you tried to follow the info from mentioned thread.

Most of the time it is a missing library that causes this.

I tried to follow the procedure in mentioned thread.
When I launch qtVlm, I get the pessage :
"error while loadin shared libraries : libpulse-mainloop-glib.so.0: cannot open shared object file: No such file or directory"
So I tried the action below
"sudo apt install libpulse-mainloop-glib0" as described in thread
Then I get the final message :
"E: Impossible de corriger les problèmes, des paquets défectueux sont en mode "garder en l'état""

Il faudrait dans ce cas plus d'info sur ce qui se passe pendant le "apt install"

pouvez vous refaire:

et nous mettre le resultat complet de la commande?
