Script for package failed with exit code 4 in SCCM 2012 R2

Problem: In SCCM 2012 R2 SP1 CU2, I’ve created a package that deploys some files such as wallpapers with a .BAT file. When I check the execmgr.log, I see the following error:

Script for Package:PR######, Program: Run Script failed with exit code 4.

Solution: Under the program in SCCM, change “Run” from “Hidden” to “Normal”.
