How do I select a RadioButton on launch in WiX v4?

[Frittions]

Hello,

Background:
I have a Burn bootstrapper application that has 3 radio buttons. The user needs to select one of these radio buttons and based on the selection different packages will be installed using 'InstallCondition' statements within the Bundle.

Theme.xml
<RadioButtons Name="RadioButtonOptions">
<RadioButton Name="RadioButton1" Value="0" X="205" Y="200" Width="-11" Height="17" TabStop="yes" FontId="3" HideWhenDisabled="no" HexStyle="0x000009">Option 1</RadioButton >
<RadioButton Name="RadioButton2" Value="1" X="205" Y="220" Width="-11" Height="17" TabStop="yes" FontId="3" HideWhenDisabled="no" HexStyle="0x000009">Option 2</RadioButton >
<RadioButton Name="RadioButton3" Value="2" X="205" Y="240" Width="-11" Height="17" TabStop="yes" FontId="3" HideWhenDisabled="no" HexStyle="0x000009">Option 3</RadioButton >
</RadioButtons>

Issue:
I want the first radio button to be auto-selected when the bootstrapper application is launched, but I cannot find a setting to accomplish this.

You defined a radiobutton control that uses the variable RadioButtonOptions and said that the buttons have the values 0, 1 and 2. But you never defined the variable or gave it a value so it doesn't know which button should be selected. You need to add this to your bundle:

<Variable Name="RadioButtonOptions" bal:Overridable="yes" Type="string" Value="0"/>

That worked! Thank you so much!
