i wanted to install "wine" so i could run some windows programs. so i downloaded the RPM. then i unpacked the package.
What do you mean with unpacking?
but now i don't know where it installed everything.
Unpacking or installing? As root or as user?
usually when i installed an RPM i could see it in my menu
Wine? I don't think so.
Use wine in the console after changing to the map, where the windows-program is located:
$ wine winprogram.exe
/winprogram/ is a wildcard for the name of the windows-program
When you are new to wine, winetools might be helpful: http://www.von-thadden.de/Joachim/WineTools/
