When you are installing Microsoft Project, you may receive the following error message:
The feature you are trying to use is on a CD-ROM or other removable disk that is not available. Insert the 'Project 2000' disk and click OK.
You receive this error message even when your Microsoft Project 2000 installation CD is currently in the CD-ROM drive.
This behavior occurs when the following conditions are both true:
- You install the retail version of Microsoft Project 2000.
- You did not uninstall a beta version of Microsoft Project 2000 that was previously installed on the same computer.
In addition, on computers that run Microsoft Windows 2000, the following conditions are also required:
- The beta version of Microsoft Project 2000 was installed when the computer was running an earlier version of Microsoft Windows, such as Microsoft Windows NT 4.0 or Microsoft Windows 98.
- You upgraded the computer's operating system to Microsoft Windows 2000 before you tried to install the retail version of Microsoft Project 2000.
During the first phase of Setup on Microsoft Windows NT 4.0, Microsoft Windows 95, or Microsoft Windows 98, the retail version of Microsoft Project 2000 upgrades the Windows Installer to a later version than the version that was included with the beta version of Microsoft Project. The upgraded version of Windows Installer cannot remove the beta version of Microsoft Project, and Setup is unable to continue.
Microsoft Windows 2000 includes the later version of the Windows Installer that Microsoft Project 2000 includes. If the beta version of Microsoft Project was installed before you upgraded to Microsoft Windows 2000, the same behavior occurs.
In addition, after Windows Installer has been upgraded to the later version, if you attempt to remove the beta version of Microsoft Project by using the Add/Remove Programs
icon in Control Panel, the Windows Installer generates the same error message that is described in the "Symptoms" section of this article.
To resolve this behavior, remove the beta version of Microsoft Project, and then run Setup again for the retail version. To do this, use one of the following methods as appropriate for your situation.
Method 1: If You Have the Installation CD for the Beta Version
If you have the installation CD for the beta version that is currently installed on your computer, run Setup again from the beta CD, and select the Remove All
option. Then you can run Setup for the retail version of Microsoft Project.
Method 2: If You Do Not Have the Beta Installation CD
If you do not have the installation CD for the beta version that is installed, you must manually remove part of the beta version, so that the retail version of Project can be installed correctly. To do this, follow these steps:WARNING
