Wix v4 Custom Theme RadioButtons

[ShakeyBones3]

I'm trying to create a custom theme for a bal:WixStandardBootstrapperApplication that uses a radio buttons to set a variable's value for an install condition. I'm able to do it with check boxes, but when I add RadioButtons to the markup the installer fails to launch. When I look in the cleanroom.log file, the only error I'm seeing is Exit code: 0xc0000005. The other log file isn't showing any errors / failures. Am I using this incorrectly or is the feature not implemented yet?

<?xml version="1.0" encoding="utf-8"?>
<Theme xmlns="http://wixtoolset.org/schemas/v4/thmutil">
	<Font Id="0" Height="-12" Weight="500" Foreground="windowtext" Background="window">Segoe UI</Font>

	<Window Width="485" Height="300" HexStyle="100a0000" FontId="0" Caption="Installer">
		<Page Name="Install">
			<RadioButtons Name="CHOICE" >
				<RadioButton Height="30" Width="30" X="33" Y="100" Value="1" />
				<RadioButton Height="30" Width="30" X="33" Y="130" Value="2" />
			</RadioButtons>
		</Page>
	</Window>
</Theme>

Start with an existing theme, then add your radio buttons, and only when that works, start removing stuff you don't need. WixStdBA assumes you have certain pages in your theme.

Sorry, I had the entire standard theme and localization file. I made an example repo here to show what I'm trying to do.

It's a bug - #7231. Also, you should add text to the radio buttons so the user knows what they're selecting.

Awesome, thanks for the help!
