Windows programs and dot net framwork

Hi all : Just installed Zorin 10 core, on laptop and will be installing the pro version on main pc, once I figure stuff out. and on that matter I navigate linux as well as I fly a B52...Im trying to install paprika recipie manager and its telling me the dot net framework 4.61 or better is required .....so now im drowning ...as simplified as possible explanation please. and thank you

Looking at their site, they seem to support everything.
Except GnuLinux.

Jerks.

Did you get a prompt when clicking the .exe to install Zorin-Windows-App-Support?

I recommend using WineTricks to install dot NET as I believe it has version 4.8

sudo apt install winetricks

In the Winetricks GUI, choose to "Install a Windows DLL or component".
Scroll down the list and select dotnet48

Typo?
Guess you mean 18 core. You should be able edit the post to correct that.
