Error 25003 on installing MS-Office

When you try to install Microsoft Office XP or any Office 2002 program from a CD-ROM or network share, you may receive an error message similar to the following:

                   Error 25003: Microsoft Office setup cannot continue because the installation source has been corrupted.

This behavior may occur when any of the following conditions is true:

• The CD-ROM is damaged or dirty
• The program files on the network share are corrupted/missing or hidden and another program that is running on your computer is interfering with the installation of Office.

To resolve this issue, use the following methods in the order in which the methods are presented.

Method 1: Clean the CD-ROM

To clean the CD-ROM, use a CD-ROM cleaning kit, or gently wipe the silver side of the CD-ROM with a soft, lint-free cotton cloth. Do not use paper cloth, which can scratch the plastic and leave streaks.

When you clean the CD-ROM, wipe from the center of the disc outward. Do not use a circular motion.

If this does not resolve the issue, clean the CD-ROM with a damp lint-free cotton cloth. Dry the CD-ROM thoroughly before you insert it into the CD-ROM drive or DVD-ROM drive.

Method 2: Show Hidden Files on the Network Share

1.      Click Start, and then click Control Panel.
2.      Double-click Folder Options.
3.      Click the View tab.
4.      Click to select the Show All Files check box.
5.      Click to clear the Hide file extensions of known file types check box.
6.      Click to clear the Hide protected operating system files check box.
7.      Click Apply, and then click OK. If this does not resolve this issue, contact your network administrator for information about how to replace the missing or corrupted files.

Method 3: Clean Boot Your Computer

Use a clean boot to restart your computer, and then see if the issue persists. A clean boot is a method to create a clean environment. When you start your computer with a clean boot, Microsoft Windows starts and loads only the basic devices and services.

To restart your computer with a clean boot, follow the steps that are appropriate to your operating system.
