--- Comment #19 from Anastasius Focht  ---
Hello folks,

please keep all unrelated problems elsewhere, including diagnosis of broken
WINEPREFIXes and/or.NET Framework installations. Wine Bugzilla is not meant for
end-user support. If you need help to set up Wine and/or app/installer
prerequisites, use WineHQ forums (https://forum.winehq.org/).

There is also the possibility to force the launcher to use a later version of
the .NET CLR. For example with .NET Framework 4.0 installed via 'winetricks -q
dotnet40':

--- snip ---
$ export COMPlus_OnlyUseLatestCLR=1

$ pwd
/home/focht/.wine/drive_c/Program Files (x86)/Zwift

$ wine ./ZwiftLauncher.exe
--- snip ---

Anyway, Ryan (comment #6) already provided decent analysis, so lets stick to
that topic.

$ sha1sum ZwiftSetup.exe 
2ff17cc55f3f6489b356c2f91f162a93947ef732  ZwiftSetup.exe

$ du -sh ZwiftSetup.exe 
2.5M    ZwiftSetup.exe

$ wine --version
wine-5.5
