I know when I put something in the log using ::MsiProcessMessage(hModule, INSTALLMESSAGE(INSTALLMESSAGE_INFO), ...); that I can check if the return value is IDCANCEL and return ERROR_INSTALL_USEREXIT to Windows installer.
How do I do that without having to put something in the log or alter the progress bar?
