Bug ID: 55070
           Summary: winemenubuilder adds incorrect prefix on 32bit only
                    Wine
           Product: Wine
           Version: 8.10
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

On 32bit (x86 only) wine, the Exec= line automatically created in an
application's .desktop file is incorrect and can not be launched.

eg: /home/gman/.local/share/applications/wine/Programs/7-Zip/7-Zip\ File\
Manager.desktop
```
[Desktop Entry]
Name=7-Zip File Manager
Exec=env WINEPREFIX="/home/gman/.wine/dosdevices/f:/home/gman/.wine" wine
C:\\users\\gman\\AppData\\Roaming\\Microsoft\\Windows\\Start\
Menu\\Programs\\7-Zip\\7-Zip\ File\ Manager.lnk
Type=Application
StartupNotify=true
Icon=EA23_7zFM.0
StartupWMClass=7zfm.exe
```

64bit (x64 with WOW64) wine does not have this issue and the generated .desktop
file will be correct.

eg: /home/gman/.local/share/applications/wine/Programs/7-Zip/7-Zip\ File\
Manager.desktop
```
[Desktop Entry]
Name=7-Zip File Manager
Exec=env WINEPREFIX="/home/gman/.wine" wine
C:\\users\\gman\\AppData\\Roaming\\Microsoft\\Windows\\Start\
Menu\\Programs\\7-Zip\\7-Zip\ File\ Manager.lnk
Type=Application
StartupNotify=true
Icon=EA23_7zFM.0
StartupWMClass=7zfm.exe
```

Both are with fresh wine installs with fresh/clean prefixes. Confirmed on
multiple devices.
