Search for launch conditions. You'll probably want an immediate custom action
(or multiple actions) to run before launch conditions
Most "features" can be traced to a service. I have a product that requires
Message Queueing, which is the MSMQ service. Here is a VB.NET custom action I
wrote using the DTF framework.
<CustomAction()> _
Public Shared Function DetectMSMQ(ByVal session As Session) As ActionResult
session.Log("Begin message queueing service detection")
For Each svc As ServiceController In ServiceController.GetServices()
If svc.ServiceName = "MSMQ" Then
session("EXISTSMSMQ") = "1"
session.Log("MSMQ was found.")
End If
Next
Return ActionResult.Success
End Function
If you had multiple required services, you could use a select/switch statement
with a property for each service. This will allow you to cancel the install if
the features are missing, but does not install them.
You cannot install the missing features from within your MSI. You'll need a
bootstrapper EXE to install the missing features. There are lots of examples of
how you do this for the .NET Framework. You'll need to figure out a command
line or API in Windows you can use to automate installing the missing features
and incorporate that into the bootstrapper. I cannot really help with that
aspect of your question.
