SCENARIO
You are deploying a package and you get an error 0x103(259). This error means that the installer you are calling exits withing 20 seconds with a code 259 and SCCM interprets it as a failure. In my case I was getting this error because I misspelled the name of a .bin file in my command line. But it may have something to do with your application as well.You can run a script to deploy the package that monitors the status of the installation and exit properly: https://social.technet.microsoft.com/Forums/windows/en-US/fbccc114-3605-4363-b983-b2f7b02fe266/program-exit-code-259-in-sccm-cllient?forum=configmgrgeneral
