When you double-click a file such as Excel.exe from an
installation source for Office, you receive the following error message:
This application requires the Windows installer to run.
Would you like to install this service now?
If you click
Cancel, nothing happens. If you click
OK, you receive the following error message:
This application must be installed to run. Please run Setup from the location
where you originally installed the application.
The Windows
Installer service is installed after you receive the first error message, so if
you double-click a file such as Excel.exe again, you only receive the second
error message.

messages. If you want to enable this functionality for this and other error
messages in Microsoft Office 2000, please download the Microsoft Office 2000
Customizable Alerts file from the Microsoft Office Update Web site at the

Web Info button in an error message, you already have Customizable Alerts
enabled.

NOTE: If you receive the error message in the "Symptoms" section of
this article when you double-click a shortcut, it may be that the shortcut was
installed by an edition of Office that is no longer installed on your computer.
To test this possibility: double-click the program file (for example,
Excel.exe), and see whether you continue to receive the error message.
