You may want to examine the CD for any scratches or scuffs.
If the CD appears fine then startup the computer in safe mode (F8).
Check the Hard drive for errors
- Right click My Computer->Properties->Tools->Check now
Copy the CD contents to your local drive
- Open My Computer
- Right Click the CD
- Choose Copy
- Right click your local disk and click paste.
- Open the copied folder and start the setup.
Hope this helps.
