These are instructions to prepare a virtual Windows XP machine for the projects.
You need these two programs installed on your computer:
VMware Player -- get it here

7-Zip: get in here
There are several files on the DVD. The only one you need is WinXPSP3.7z.
Copy that file to your computer, right-click it, and extract it with 7-zip.
Then open the extracted .vmx file in VMware Player.
