How do I associate file types in VS Setup project with a condition?

I need to ask for user's permission to change video and audio file associations on their computer, so I added a checkbox UI to the setup project in VS2010. My problem is that I don't see a condition for file type associations in the relevant editor to link to the checkbox property.

Doesn't VS setup and deployment project provide this functionality? Any ideas?

EDIT:

It was pointed out that Visual Studio setup projects don't have an option for conditional file associations. I am now using Orca to edit the .msi tables directly. Has anyone been able to introduce conditions for file type associations by modify开发者_Go百科ing the Condition table of the .msi package, or something like that? How am I supposed to do this?

Windows Installer doesn't support conditional file associations.

So a solution would be to use a custom action to create them instead of the native support. You can then condition this custom action with your checkbox property.
