[WiX-users] How to track Exit button click in windows installer

[Jignasha V S. <jig...@az...>]

 
We are developing installer where in we need to rollback all the action if
user clicks cancel inbetween. When user clicks cancel it opens Dialog with
the option of Resume and Exit. We need to rollback only when user click exit
option. As a part of installation we are running VBScript file. 
    We are facing problem to handle Exit button click in VBScript file. Does
anybody know how to handle Exit button click in VBScript file while running
the msi.
 
Thanks,
