Specifying Operating System Requirements in the Project Assistant

InstallShield 2026 Express Edition

When you specify operating system requirements on the Installation Requirements page of the Project Assistant, InstallShield creates launch conditions. These conditions are added to the LaunchCondition table of your .msi file.

How InstallShield Creates the Operating System Launch Conditions

When you specify operating system requirements on the Installation Requirements page, you are essentially excluding operating systems that do not support your application.

For example, if you select only the check box for the latest Windows operating system, InstallShield creates a launch condition to exclude the operating systems that you did not select on the Installation Requirements page. With this type of launch condition, future versions of Windows operating systems are supported automatically because they are not excluded in the launch condition.
