Wine is a preferred windows emulator when you want to run native Windows applications on Linux. Here is how easy is to install Wine on Ubuntu 20.04
For more information on Linux, I recommend taking the Practical Ubuntu Linux Server for beginners course.
Just follow the steps:
1) install wine32 first in order to include the i386 libraries:
apt install wine32 and wine
2) install winetricks in order to easily install external windows libraries. If you want to know which libraries are required just run wine your_app.exe and check the produced log:
apt install winetricks
3) use winetrics dlls combined with the libraries required by your application:
winetricks dlls mfc42 vcrun2010
4) run wine somefile.exe
Congratulations, and if you would like, you can enjoy the full Ubuntu admin course !
