I installed Wine using synaptic but when I write "Wine" in Launcher the only results are:
Configure Wine
Uninstall Wine Software
Winetricks
Is this normal? Shouldn't there be an instance of Wine?
That is the normal behaviour for about as long as I have used Wine (~4 years). Wine does not do anything by itself, it is always used for running something else:
$ wine
Usage: wine PROGRAM [ARGUMENTS...] Run the specified program
wine --help Display this help and exit
wine --version Output version information and exit
Programs installed in Wine usually get their own launchers.
winemine
. I also think there is some other stuff for building windows packages for Linux.
