This is what I want you to do. Go to your desktop and make a new folder called 'Sims' (right click on desktop - new folder). Then, Go to My Computer and right click the cd drive. In the menu, click 'Open'. When it opens, you should see a heap of files. Hold down control and press 'A'. All of the files should be selected. Then hold down control and press 'C'. Go back to your desktop and open up the Sims folder. Hold down control and press 'V'. It will take a while, but when all of the files are copied, find a file in the folder called 'setup' or something along those lines. Open it and see how you go.
