如果用户同意对话框，Wix安装程序如何创建注册表项？

Question

I am creating an installer in Wix. I need a simple dialog during the installation where the user has to agree something, if they do, I want to create a registry key recording this choice.

This seems the simplest of tasks, but how do I use Wix to create the dialog and conditionally create the registry key based on the user's input?

So far I've tried to find out about custom actions, but it seems that this is not the right tool as Wix contains the ability to create a registry key already. I just don't know how to tie installation of a feature to the response to a specific dialog. If the agreement is not given, then the installer should continue as normal, just without this specific registry key.

I'm using Visual Studio.

Some code snippets: This is at the top of my product, next to the other properties.

<Property Id="STREAMING_ACCEPTED" Secure="yes"/>

Then I have a dialog with the following control element.

<Control Id="StreamingAcceptedCheckBox" Type="CheckBox" X="20" Y="207" Width="330" Height="18" CheckBoxValue="1" Property="STREAMING_ACCEPTED" Text="Accept streaming" />

And finally, I'm trying to hook this up by adding a condition to the component.

<Component Id ="StreamingAcceptanceRegKey" Guid="some-guid" Win64="yes">
  <Condition>STREAMING_ACCEPTED</Condition>
  <RegistryKey Root="HKLM" Key="SOFTWARE\MyProgram" ForceCreateOnInstall="yes" ForceDeleteOnUninstall="yes">
    <RegistryValue Type="string" Name="UsageStats" Value="true" Action="write" KeyPath="yes"/>
  </RegistryKey>
</Component>

Am I on the right lines, because it's not writing the registry key? Does this actually record "true" and "false" to the property based on the checkbox state?

Answer 1

The UI control has a property associated with it. Make sure it's a secure custom public property. (All caps and marked secure ).

Describing how feature selection and INSTALLLEVEL works in an MSI takes some time. Since you only have 1 registry value I would instead suggest creating a component to set the registry value and putting a condition on that component that uses the secure custom public property found in the UI.

If you want to support the user going into Programs and Features and changing the original choice then make sure you mark the component as transitive and implement a WiX remember property pattern so that subsequent repairs / transactions keep the choice.
