I am triying to install the desktop app in my pc. I double clic the installator, then it show me the splash screen and a shortcut is created in my desktop (It does not ask me to enter the credentials). I double click the shorcut created and it adds a notification icon in the task bar, after some seconds it dissapears. I try to reinstall but it does not work.
I have the same problem. I logon to the online version of Teams and download the Desktop App. It downloads a setup that is about 67MB of size. After I launch the setup it only copies some files to C:\Users\%UserName%\AppData\Local\Microsoft\Teams and creates a desktop shortcut that points to C:\Users\%UserName%\AppData\Local\Microsoft\Teams\Update.exe --processStart "Teams.exe". When I try to launch the app, two teams.exe processes are started, a small notification icon is shown in the system tray, then the processes stop an the icon disappears.
I tried to uninstalled the app and restarted my comupter severel times, but no luck.
