Evaluate the search operation

Use the [Evaluate… ] button to test your search while an item or multiple items from the list are selected.

Specifying the order of the searches

The order in which the searches will be performed when the condition is evaluated matches the order showed in the list. Use the[Up ] / [Down ] buttons or the “Up” / Down context menu items to change it.

Install only if at least one condition is false

If this option is selected, at least one search must fail in order to install the prerequisite.

Install only if all conditions are false

If this option is selected, all searches must fail in order to install the prerequisite.

Install only if this prerequisite is being installed

Choose another prerequisite that conditions the installation of this prerequisite. If the selected prerequisite is not being installed, this prerequisite will not be launched.

Use 64-bit locations when evaluating conditions on a 64-bit machine

By default the prerequisite uses 32-bit locations on a 64-bit machine. This applies to registry locations and Windows Installer Properties like [ProgramFilesFolder], [SystemFolder], [WindowsFolder], etc. For example [SystemFolder] property is resolved to “C:\Windows\Syswow64” folder path if this flag is disabled.
