RESOLUTION
To resolve this problem, follow the appropriate steps.

 * 2) In the Open box, type the following command line, and then click OK:  \Setup.exe /fv  .msi

Where  in this command line is the path of your Office Setup files on your installation CD, and   is the version title of the Windows Installer file that corresponds to the version of Office that you are installing, for example, type d:\Setup.exe /fv pro11.msi.

If You Are Trying to Install Office 2003

 * 1) Click Start, and then click Control Panel.
 * 2) Double-click Folder Options.
 * 3) On the View tab, under Hidden files and folders, click Show hidden files and folders.
 * 4) Open the \Windows\Installer folder on your computer's hard disk.
 * 5) Right-click any file that has an .msi extension, and then click Properties.

The Subject box on the Summary tab contains the name of the product that installed the Windows Installer file.
 * 1) Repeat step 5 for each Windows Installer file in the \Installer folder, and then delete the Windows Installer file for the version of Office that you are trying to install.
