--- Comment #12 from Fabian Maurer dark.shadow4@web.de --- Some things to look out for:
Use a fresh 32bit WINEPREFIX
Use wine-2.22 to run "winetricks -q dotnet45", because staging might freeze.
use wine-staging-2.22 for running the program with "wine runas /trustlevel:0x20000 SourceTreeSetup-2.3.5.0.exe". Btw, wine-staging-2.22 isn't released yet, you either have to wait or patch it yourself.
