The Launch Conditions Editor can be used to specify conditions that must be met in order to install successfully on a target computer. For example, if your application is designed to run only on Microsoft Windows 2000 or later, you would specify the condition VersionNT>=500. When the installer is run, if the condition evaluates to false then an error message will be displayed and the installation will be aborted.

1. Select the Launch Conditions node in the Launch Conditions Editor.
2. On the Action menu, choose Add Launch Condition.

   The new condition is highlighted in the conditions list.

3. Type a name for the condition.
4. In the Properties window, select the Condition property and enter a valid condition.

   Note   To learn more about condition syntax, see Deployment Conditions.

5. Select the Message property and type the text for the error message that will be displayed if the condition evaluates to false.
