wine-5.20 stagging: Prompt to install wine-mono but it is already installed

[postcd]

Hello,
on 5.8.18-1-MANJARO with wine-5.20 (Staging) i have for the first time tried to launch Windows app, it was .exe installer of https://sourceforge.net/projects/visual ... c%201.0.1/ and it said something like that it needs wine-mono installed and prompted to download or install it. But i refused wanting to install it via command line as a package so i said No. It then continue to show that .exe app installer. I closed it.
Checked command line to see the package was already installed (so i do not understand why Wine asked me to install it?):

$ sudo pacman -Ss wine-mono
community/wine-mono 5.1.0-1 [installed]
Wine's built-in replacement for Microsoft's .NET Framework

but there seems to be some similar packages in unofficial Manjaro/Arch repos:

$ sudo pamac search -a wine-mono
wine-mono-gecko-version-fix 1.0.0-1 AUR
Fix the version numbers of wine-mono and wine-gecko files to solve the dialog box that pops up when starting wine.
wine-mono-bin 5.1.1-1 AUR
Wine's built-in replacement for Microsoft's .NET Framework
wine-mono [Installed] 5.1.0-1 community
Wine's built-in replacement for Microsoft's .NET Framework

On next .exe app launch it no longer prompt about wine-mono. It seems strange to me. Is this something that can be fixed?

When i launched winetricks 1st time, i have got "You are using a 64-bit WINEPREFIX. Note that many verbs only install 32-bit versions of packages. If you encounter problems, please retest in a clean 32-bit WINEPREFIX before reporting a bug."

So i read how to setup 32bit prefix and ran command:
WINEPREFIX="$HOME/prefix32" WINEARCH=win32 wine wineboot

result is again the "Wine could not find a wine-mono package" notice. It also says it is recommended to use my distribution packages instead so i clicked to cancel.

above WINEPREFIX command returned bunch of errors too:

wine: created the configuration directory '/home/me/prefix32'

wine 5.20 requires mono 5.1.1, mono 5.1.0 is for 5.10-19. When the mono in the repos is outdated, wine asks you if it should fetch mono manually. If you don't need mono, you can always click no and wait, till the version in the repo is updated.

And of course it no longer asks, if you have already declined it.

wait, till the version in the repo is updated.

Thanks, I will, btw, when i click yes to install it on that prompt window, it says "Unexpected checksum of downloaded file. Aborting installation of corrupted file."
