FYI I can't reproduce it here with Wine 5.5. It successfully installed ten consecutive times, each with clean 64-bit WINEPREFIX.
FWIW, with winetricks-test, it's relatively reliable.
Running dotnet471 in a loop of 1000 last night, didn't fail until iteration #107.
winedbg hung when I tried to dump info. Not sure if it was machine state or a wine regression, I'm retrying with WINEDEBUG set (and will try other wine versions if needed).
