What does not
Installer does crash the first time (Wine debug window). The next times the installer does immediately shows this error window: "Installation has failed, please re-run this installer as a normal user instead of 'Run as Administrator'."
What was not tested
Completing the installation.
My setting: export WINEARCH=win64 && export WINEPREFIX=$HOME/.wine-github-desktop
OS set as "windows 7" (winecfg).
