How do I mark a directory to be deleted after reboot?

Question

I've got an uninstaller that performs some actions and then prompts the user to reboot. I'd like a directory to be deleted after the reboot takes place. I know there's a way to do this, I'm just not sure how.

I'm using a WiX installer, and I'd imagine I could use that to do so, somehow, but I'm open to alternatives (whatever's simplest is just fine with me). My target platform is Windows 7, though it would be nice if this worked with older versions of Windows as well.

What's the simplest way to mark this directory for deletion after a reboot?

Answer 1

If you have a locked file condition Windows Installer can handle the deletion after the reboot but there is no built-in way of instructing it to only delete it after a reboot. I think the only way you could do it would be to use a custom action to record a RunOnce registry entry that instructs it to do the delete. You can't use the Registry table for this as Windows Installer has no way of recording to the registry as part of an uninstall.

Still, you are coloring outside the lines on this one so I'd want to understand the why of this requirement in determining if it's valid.
