Cancel Installation of Wix Burn Boostrapper and Remove ARP Entry

I have a Wix Bootstrapper that, for the cases solving this issue, installs a single msi. If the user cancels mid installation, or the installation is unable to complete due to files in use, the bootstrapper starts the rollback process. The partially installed msi is properly cleaned up and files are removed. However, the ARP entry for the wix bootstrapper is still present. There are no other installed msis. Nothing is marked as permanent. It would seem to me that the ARP entry should be removed as nothing was installed. Here's the XML:

Vital Attribute: I think the cause is that you have set the MsiPackage to be Vital="no". When you do this you tell the Bundle to keep installing even if it rolls back the MSI in question. So please try setting Vital="yes" and test again.

Comments: Note that I tested with a test bundle and not your code above - the main difference being your custom bootstrapper application, and me using the default one. So there could be other causes for the problem seen - for example your custom bootstrapper application or the RelatedBundle construct that I have never tried.
