bootstrapper application rollback

I am trying to create a Wix burn bootstrapper that installs my msi. The bootstrapper exe is working fine but the only issue is that whenever I try to cancel the installation in midway the custom actions which are added in msi is not get stopping. Can anyone tell how to stop and rollback the installation while clicking cancel button. Thanks in advance.

A custom action must send ::MsiProcessMessage() calls to provide the possiblity to recieve the cancel and handle the return code from that API (usually ERROR_INSTALL_USEREXIT or IDCANCEL). Then the custom action must exit.

If you look at some of the WiX standard custom actions you'll see lots calls to WcaProcessMessage() and such. We save the return code from those and WcaFinalize() returns the correct thing on exit. Check out src\ca\wcautil\wcautil.cpp and src\ca\wcautil\wcawrap.cpp for example code.
