I have some nice windows application installed by wine, but it's inconvenience to invoke it from the terminal. Therefore, i made a .desktop file for it(DVDFabDecrypter.desktop) and put it in /usr/share/applications/. However, i still dont see it in the gnome menu! Is there anything i have to do? This is the content of the desktop file:
[Desktop Entry]
Encoding=UTF-8
Name=DVDFab Decrypter
Exec=wine /WinApps/DVDFab\ Decrypter/DVDFab\ Decrypter.exe
Type=Application;AudioVideo;
Comment=DVD decrypter
Icon=/usr/share/pixmaps/DVDFabDecrypter.xpm
GenericName[en_US]=DVDFab Decrypter
Terminal=false

Maybe running update_desktop_database would help? I know that caches the MIME types from desktop files, but it's possible that GNOME uses it to add .desktop files to menus? As you can probably tell, I don't know what I'm talking about that much, but it's worth a try.

Well, i see the word MIME somewhere but i dont know what it is, can you explain? Moreover, i notice that the file DVDFabDecrypter.desktop i created is just a text file which means it does not have the launcher tab in it's properties! Other desktop files has the laucher tab, so how can i made it become a launcher? i tried update-desktop-database as root but nothing happened.
Thanks for the suggestion

In that case, maybe you should make sure the permissions are set so it's executable and that it doesn't have a .txt extension (since it's recognized as a text file)? Sorry, that's all I can think of.
