: You cannot extract "part3.rar" by itself. You must have all other parts (Part 1, Part 2, etc.) in the same folder before you begin.

: Locate setup.exe or a similar file to begin the installation on your PC.

: Right-click on Part 1 and select "Extract Here." The software will automatically pull data from Part 2, Part 3, and so on to reconstruct the full file. You do not need to repeat this for each individual part.
