Implication

Target operating system

The target system must have one of the following operating systems, or a later version:

Windows Server 2003
Windows Vista
Windows XP SP1

Consider adding a launch condition so that end users can install the product only on platforms that support installing multiple instances of products.

Tip: You can use the Installation Requirements page of the Project Assistant to quickly add launch conditions to your project. For more information, see Specifying Operating System Requirements in the Project Assistant.

Windows Installer version

Windows Installer 3.0 or later is required.

If target systems may not have Windows Installer 3.0 or later, consider adding the Windows Installer redistributable to your project.
