Hello Prashanth,
Yes, it is possible to do that.
There are actually two ways of achieving this:
1. you could add the .EXE as a
prerequisite to your other project
2. you could launch it through a
"Launch File" custom action. However, please note that here you can not schedule the custom action everywhere, because Windows Installer allows only one MSI-based installation to run at any given time. The setup should either be launched before the installation starts (before the
"Install" button is pressed) or after the installation ends.
Best regards,
Catalin
