If you are prompted with a menu, click on Mark for Install. Then on the top left corner click on Installation > Apply Changes.

At the bottom “System Variables” panel, add to the “Path” variable: C:\MinGW\bin or the full address of that folder if you have used a different one during the installation. Click on OK, and OK and close the other windows.

5. Open a Command Prompt Terminal and try typing gcc –version and press <Enter> to check if it works.
