I am creating a WIX Bootstrapper using WIX Burn. The resultant bundle "exe" will be consumed by another application or rather a MetaInstaller. Now the application executes the bundle as a process with arguments but we don't want to make any entry in ARP for the bundle.
Is there any way to achieve that?
Yes. In the Bundle element, set these attributes
<Bundle DisableRemove="yes" DisableModify="yes"
DisableRemove
If the "DisableModify" attribute is also "yes" or "button" then the bundle will not be displayed in Progams and Features
You should note, however, WiX burn is a package manager. So you should ensure that your uninstallation process invokes it to clean up the bundle and unused non-Permanent packages.
