When you insert a Microsoft Office CD-ROM, either to repair an Office installation or to install a feature set to Installed on First Use, you may receive the following error message:

Back to the top

This problem can occur if all the following conditions are true:

•	You originally installed Office from a network administrative installation.
•	The network administrative installation is no longer available to you.
•	You are trying to use an Office CD-ROM when you are prompted by the Windows Installer for an Office source location.
•	You click Cancel when you are prompted to insert the CD.

Because the files in an administrative installation are uncompressed, and the files on an Office CD-ROM are compressed, the Windows Installer cannot resolve the differences between the two source types.

The resolution to this problem depends on whether you can obtain access to a network administrative installation. Use the following methods, as appropriate to your situation.

Use an Alternative Network Administrative Installation

If the original administrative installation from which you installed Office is not available, you can use a different administrative installation for the Office source file location. To do this, follow these steps:

1.	Click Start and then click Run.
2.	In the Open box, type a command line similar to the following, and then click OK new network path\Setup.exe /fvm package name.msi where new network path is the full path to the alternative network administrative installation, and package name is the name of the Windows Installer .msi package on the root of this administrative installation (for example, Proplus.msi).
3.	Click OK when the update is finished.

Note After you follow these steps, the Windows Installer uses this new server location whenever it needs to reinstall, repair, or add a feature to your Office installation.

Create an Administrative Installation on Your Computer's Hard Disk

If you do not have access to a network administrative installation but have more than 700 MB of free disk space on your hard disk, you can create an administrative installation on your hard disk to use as the Office source file location. To do this, follow these steps.

Note To create an administrative installation, you must use an Enterprise edition of Office.
