I solved this same issue with a custom action on the next button of the
feature selection dialog. I tried solving it within Wix/Windows Installer
but was unable to.
The pseudo-code is something like this...
<Publish Dialog="CustomizeDlg" Control="Next" Event="DoAction"
Value="CAMustSelectOne" Order="1">1</Publish>
<Publish Dialog="CustomizeDlg" Control="Next" Event="NewDialog"
Value="VerifyReadyDlg" Order="2"><![CDATA[ATLEASTONESELECTED <>
"0"]]></Publish>
Custom Action looked something like this (error handling and exception
management removed for brevity):
// these are all hidden or "container only" features,
// if they are selected for install, they are not considered a "real"
feature
private static readonly string[] IgnoredFeatures = { "Server", "Logs",
"Data", "WebSites", "WindowsServices", "Tools" };
[CustomAction]
public static ActionResult MustSelectOne(Session session)
{
ActionResult installResult = ActionResult.Success;
// assume we success until told otherwise
session["ATLEASTONESELECTED"] = "1";
if (NoFeaturesSelected(session))
{
session["ATLEASTONESELECTED"] = "0";
MessageBox.Show(new Form() { TopMost = true }, "One or more
features must be selected");
}
return installResult;
}
private static bool NoFeaturesSelected(Session session)
{
return session.Features.Where(feature =>
!IgnoredFeatures.Contains(feature.Name)).All(feature =>
feature.RequestState != InstallState.Local);
}
