When you try to use a feature in Microsoft PowerPoint 2000 that is not installed, you are prompted to insert the Microsoft Office 2000 CD-ROM. When you insert the CD-ROM, you may receive an error message that is similar to the following:
Error 1603 Error_Install_Failure
This behavior occurs when all the following conditions are true:
You have Microsoft Office Standard, Professional, or Small Business Edition installed on your computer.
You then install a different edition but the same version of Office -- either Office Professional or Premium Edition.
When you attempt to use a feature that is not installed, you insert the most recently used Microsoft Office CD-ROM into the computer.
Setup is expecting the CD-ROM from the first installation of Microsoft Office.
To work around this issue, use one of the following methods.
Method 1: Insert the Earlier Office CD-ROM
When you are prompted for an Office CD-ROM, use the appropriate disc from the first Microsoft Office edition that was installed on the computer.
Method 2: Reinstall Office
Follow these steps to reinstall the most recent edition of Microsoft Office:
Insert the Office CD-ROM that was installed last.
Click Start, click Run, and then type MSIEXEC /i drive:\data1.msi reinstall=all reinstallmode=vomus in the Open box, where drive is the letter of your computer's CD-ROM or DVD-ROM drive.
