RE: [WiX-users] Conditional installation of features

[Riko E. <ri...@ko...>]

Hi

I am of the "stick-to-MSI-rules-because-they're-good-for-you"
orientation, and generally when you get to the point where you have to
resort to a "really icky solution" it might just suit you better if you
rethink the way your install works.

In this case, I would agree with Jason, who suggested you rather use the
AddLocal/AddSource/Remove/SetInstallLevel actions from UI controls
instead of trying to toggle the feature conditions after CostFinalize.
Basically, MSI works like this:

* decide what features you want to present to the user (before
CostFinalize)
* the user chooses the features he wants to install (after CostFinalize)
* you install the features the user selected

So if you have to do something which you shouldn't be doing (like
setting feature conditions after costfinalize) it's usually a sign that
you're doing something the Windows Installer designers THOUGHT you
shouldn't be doing. And best to find another way.

A good example is the good old "Full install, Minimal Install, Custom
Install" screen. If you decompile one or two standard installs, you'll
see that selecting full install usually does an ADDLOCAL=3DALL thing.
While selecting Minimal install usually sets INSTALLLEVEL=3D1 or =
something
similar.

My suggestion, come up with a different way to design your UI. If you
explain what you want to do, and post it here, myself and many others
would be more than willing to help.

Sorry for the rant <smile/>

Maybe. Do you have a better solution?
I think it is possible as SelectionTree chooses features at UI runtime.
What I try to implement is a set of mutually exclusive features,
choosable thru radio buttons.
A working fragment would be highly appreciated.
