[wix-users] Burn engine hangs when run silently

[dylanalpiger]

Hello everyone,
I've been experiencing some Burn troubles lately, and was hoping the Wix community could shed some light on the issue. 

I have a custom Wix bootstrapper. For the most part, the installer will run fine and finish successfully. However, periodically the installer will complete the installation process (install all packages and perform all Custom Actions), but will hang just before it shuts down. I stepped through the burn project, and it looks to me like the message pump in RunApplication() (engine.cpp) is never getting the quit message it needs to finally quit the pump and proceed to the method's completion. The installer enters this state once the CoreApply() process competes. Has anyone else dealt with this (or a similar) problem before?
Let me know if you need more information. Any insight you can provide would be greatly appreciated.
Thanks!Dylan
