Help with Conditional Statements in Basic MSI Project

I have three 3rd party applications to "possibly" install along with my application installation.

DirectX 9.0c Redist (June 2008)
.NET Framework 3.5
Another Application

I've read the forums... dug through the help documentation.. but can't for the life of me find an instance of a conditional check for the application alreadying being installed.

These are not InstallShield Prerequisite's... They can be run after the installation... and the client would like them to be silent installations.

Any help would be greatly appreciated.

If the question is how to detect if other software is installed, you can often set up a system search to look for proof: a particular version of a file somewhere, or a registry value.

As for running the other installers, it depends on your requirements; InstallShield 2009 supports feature-based prerequisites, for example.
