I have two unrelated Windows programs that come with their own setup.exe files. Using a third-party tool, how do I bundle the two in a single installer? The setup wizard functionality would work like this:

1. They run my setup.exe. It's primary goal is to install Windows program A.
2. On page 2 of the installer, it has a checkbox to install Windows program B.
3. When they click Next on page 2, my installer window vanishes and Windows program A's installer runs.
4. When that installer finishes, my installer detects this. If Windows program B was selected to also be installed, its installer runs next, and again with my installer window not shown.
5. When step 4 is done, my installer detects one or both installs are finished and shows a Finish page from my installer. The user clicks that and my installer closes because it has concluded its purpose.
