Build Error: The specified task executable "cmd.exe" could not be run

Problem:
Though Example program could run from /bim/debug/.exe file, After “build” the following err displayed as seen in log file…

1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppCommon.targets(133,5): error MSB6003: The specified task executable “cmd.exe” could not be run. The requested operation requires elevation
1>Done Building Project “C:\nsb\setups\OpenFrameworks\of_v0.9.8_vs_release\apps\myApps\soundPlayerExample\soundPlayerExample.vcxproj” (Build target(s)) – FAILED.

Soln:
Sound Player Example - Properties
Build Events ->Post-Build Event -> Command line
robocopy “$(OF_ROOT)/export/vs/$(Platform_Actual)/” “$(ProjectDir)bin/” “*.dll” /njs /njh /np /fp /bytes if errorlevel 1 exit 0 else exit %errorlevel%

Remove Above line from command-line
OK, Solved.
