I'm currently learning how to implement custom BA's through WIX and happen to
run into a road block. I've created a custom GUI through WPF and need pass
back to the WIX bootstrapper app, variables that I set in the C#
application.
Here is my C# function that calls the Bootstrapper app
private void InstallAExecute()
{
IsThinking = true;
Bootstrapper.Engine.StringVariables["AToInstall"] = "A";
Bootstrapper.Engine.Plan(LaunchAction.Install);
}
and in my Boostrapper app, I have the following element <Variable Name
="AToInstall" bal:Overridable="yes" Value="A" Type="string"/> declared above
my BootstrapperApplicationRef element.
Then in my element Chain, I would like to add a conditional to trigger a
particular msi to be installed when the variable satisfies the condition.
This is what I have in my chain, but I think my syntax is incorrect.
<Chain>
<PackageGroupRef Id='Netfx4Full' />
<MsiPackage SourceFile="..\Path\To\Installer.msi"
Id="InstallationPackageId" Cache="yes" Visible="no" InstallCondition
="AToInstall=A"/>
</Chain>
Any idea where I went wrong?
