Hello folks,

the failure is expected. The installer checks the registry using the MS
recommended way for .NET Frameworks installation.

Wine-Mono advertises itself as .NET Framework 4.5 in registry hence the
installer will try to run MS .NET Framework 4.7 installer. This can't work by
design as long as Wine-Mono is installed in WINEPREFIX.

You can of course always work around by using 'winetricks' which has recipes
for various MS .NET Frameworks, including proper uninstallation of Wine-Mono.

App installer has a hard-coded check for:

Release: 0x707FE -> 460798 = .NET Framework 4.7.0 as minimum

NOTE: The Wine-Mono installer version scheme doesn't correspond with MS .NET
Frameworks scheme. This is a common misconception of users.

http://dl.winehq.org/wine/wine-mono/4.7.3/ -> has nothing to do with MS .NET
4.7 compatibility.
