When you try to install an "advertised" component in a Microsoft Office 2003 program, you may be prompted to insert your Office 2003 CD.

This problem may occur if any one of the following conditions is true:

• The Msocache folder was not created while the Office 2003 Setup program was running because of a lack of free disk space--for example, free disk space was less than 1.5 gigabytes (GB).
• The Msocache folder was not created while the Setup program was running because of the intentional use of the CDCACHE=0 option during the installation of Office 2003.
• The Msocache folder was created, but only selected features were installed because of available free disk space between 1.5 and 2.5 GB (CDCACHE=1).
• The Msocache folder content (cab files) were removed at the end of the Office Setup program.
• The Msocache folder content (cab files) were removed by the Cleanup Wizard.
• The Msocache folder or its contents, including the bootstrap files, were manually deleted.

To work around this problem, use the Local Installation Source Tool. To download the Local Installation Source Tool, visit the following Microsoft Web site:

The Msocache folder is created as a local installation source for your Office 2003 installation. When the Office 2003 Setup program requires source files, instead of prompting your for your Office CD-ROM, the Setup program uses the local installation source (the Msocache folder) for the files that are required to complete the Setup program.

The Msocache folder is a hidden folder and resides at the root-level of the drive that you installed Office. If you have multiple hard disk drives, the Msocache folder will reside at the root-level of the drive that has the most available space.
