Hello everybody!
There is the way to silent installation. Like this
"launcher.exe /install /silent /allusers=yes /setdefaultbrowser=no /language=en-us"
But I can't find the way to the same silent uninstallation.
"launcher.exe /uninstall" just launches the Unistallation window. I can't find the "uninstall" proper switches
Please help! Thanks!
