Launch Condition Management in Deployment
The Launch Conditions Editor allows you to specify conditions that must be met in order to successfully run an installation. For example, you might want to check for a specific version of an operating system — if a user attempts to install on a system that does not meet the condition, the installation will not occur.
Searches can be performed on a target computer to determine if a particular file, registry key, or Microsoft Windows Installer component exists.
Predefined launch conditions allow you to add a both search and a launch condition in a single step. The Property property for the search is automatically referenced in the Condition property of the launch condition.

Searches and conditional evaluations are performed at the beginning of an installation.
