No Wine menu showing up in main menu

Solution 1:

Rather than actually delete anything, menu editors on Linux simply mark menus as "Deleted" so that they don't show up in the menu. First, see if the directory is in your menu editor and can be re-enabled.

This information is stored in ~/.config/menus/applications.menu . Edit ~/.config/menus/applications.menu and you should find a section near the end that looks similar to this:

    <Menu>
            <Name>wine-wine</Name>
            <Deleted/>
    </Menu>

or perhaps this:

    <Menu>
            <Name>wine-wine</Name>
            <Menu>
                    <Name>wine-Programs</Name>
                    <Menu>
                            <Name>wine-Programs-AutoHotkey</Name>
                            <DirectoryDir>/home/user/.local/share/desktop-directories</DirectoryDir>
                    </Menu>
            </Menu>
            <Deleted/>
    </Menu>

Remove the <Deleted/> line and your Wine menu will reappear.
