Detective Gallo works in gnu/Linux using Wine 4.0 (staging); however it requires a bit of setup.


First, create a new wine prefix with no default dot net libraries...

$ export WINEDLLOVERRIDES="mscoree,mshtml="
$ export WINEPREFIX="/path/to/installation/directory/"
$ export WINEARCH=win32
$ wineboot -u


Install the libraries in the the wineprefix ..

$ unset WINEDLLOVERRIDES
$ winetricks -q dotnet472
$ winetricks -q vcrun2017


Finally install the game...
$ wine setup_detective_gallo_1.1_\(22075\).exe

At the end of the setup you may get some errors, but they are harmless.


To play set up the WINEPREFIX variable and exec the main executable
$ export WINEPREFIX="/path/to/installation/directory/"
$ cd "/path/to/installation/directory/drive_c/installation/directory/"
$ wine ./Detective Gallo.exe
