Right-click on part01.rar and select "Extract Here" (using WinRAR or 7-Zip). It will automatically pull data from part09 and the others.

Run the setup.exe found in the extracted folder.

Ensure part09.rar is downloaded along with all other required segments.

If the extractor asks for "part09," ensure this file is named exactly as shown above and sits in the same directory as part01.
