nest installation hyper link is busted

[TurboFisch]

main custom action page and the help where it reads

"....To learn more, see Concurrent Installations in the Windows Installer Help Library. "

takes you to the French page that says
"Contenu introuvable
La page demandée est introuvable. "

so where is the help?

In InstallShield 2012 Spring that link takes you to:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/concurrent_installations.asp

But that's a dead link on msdn.

A msdn search of "Concurrent_installations" finds:
http://msdn.microsoft.com/en-us/library/aa368010(v=vs.85).aspx

That says:

Concurrent Installations, also called Nested Installations, is a deprecated feature of the Windows Installer. Applications installed with concurrent installations can eventually fail because they are difficult for customers to service correctly...

so if one has to launch another msi, what is the alternative?
