Winetricks is a helper script for downloading and installing various redistributable libraries needed to run some programs in Wine, as well as setting up the environment.
As usual, before installation, you need to make sure that you have all the system updates installed and that the latest drivers are present.
To install winetricks, you need to open the terminal and enter the commands one by one:
chmod +x winetricks
This completes the installation of winetricks. Next, you can install additional libraries in your WINE and PlayOnLinux prefixes.
In PlayOnLinux, it is better to use winetricks instead of the provided libraries inside PlayOnLinux.
