--- Comment #52 from Andrew Church achurch+wine@achurch.org --- The launcher didn't try to install anything in my prefix (set to Windows 10), just updated itself and started normally under wine-10.0 with patched mshtml/jscript DLLs from my gitlab repo. So the solution may just be "make sure the prefix is set to Windows 10" (or possibly Windows 11, untested).
