Hi,
I have found that the push installation is very unreliable. For instance, if there is not enough disk space on the target client and the install fails, the PDF will report success. I did have workflow checking the success of the package build, then it would deploy the code to the logic servers & Fat clients (You cannot push install to Cistrix Servers), and mail the appropriate people of the success, but I never took it to production as the PDF is not always accurate.
Let me know if you want any more information.
