Note You may it helpful to print this article before you try the resolution methods.
Method 1: Clean the discUse a disc-cleaning kit to clean the setup disc. Or, gently wipe the silver side of the disc by using a soft, lint-free cotton cloth. Do not use paper cloth, which can scratch the plastic or leave streaks. When you clean the disc, wipe from the center of the disc outward. Do not use a circular motion. If the problem continues to occur, clean the disc by using a damp cloth or a commercial DVD cleaning solution. Dry the disc thoroughly before you insert the disc into the disc drive.
Visually inspect the DVD for dust or fingerprint smudges. If the DVD is scratched, the information on it may not be retrievable, and you might have to obtain a replacement DVD to install the Office suite.
To obtain a replacement disc from Microsoft in the United States, telephone the Microsoft Order Desk at (800) 360-7561. If you are outside the United States, please visit the following Microsoft website to learn how to obtain a replacement disc:

Method 2: Test the DVD driveTry to install the application by using a different DVD drive on the same computer, or use the same disc and install the product on a different computer. If the installation is successful and if you can start the application, the problem may be that the original DVD drive cannot read the product disc.
If the problem continues to occur, the disc might be damaged. For information about how to replace the disc, see Method 1. If the problem did not recur, go to Method 3.
Method 3: Copy the installer file to your desktop
If the file can be copied without error, try the installation from the installer on the Desktop. If an error occurs, go to Method 4.
Method 4: Try the disk in safe boot modeIf the problem continues to occur, background programs/services that are running on your computer may be preventing setup from completing. You can use safe mode to troubleshoot the problem. For more information about safe mode, click the following article number to view the article in the Microsoft Knowledge Base:

Method 6: Check for antivirus softwareAn antivirus program may be conflicting with the installation. Be aware that during the installation of Office, Setup prompts you to quit all applications and turn off antivirus software before you continue. If you do not quit the antivirus program, Office might be unable to perform the installation.
