Running BGInfo during Task Sequence not loading.

I am trying the stock method at the moment: In my Task Sequence at the very start I have the "Use Toolkit Package with MDT2012 package".  Im then running run command line with:
cscript.exe "%SCRIPTROOT%\ZTISetBackground.wsf" /image:1
I see a brief CMD window for half a second but the BGinfo doesnt pop up it still has my PE background.  The logfile said ZTISetBackground.wsf could not find the BGinfo.exe although the toolkit package has been used and not modified.  

This a non MDT Task Sequence but one I have made in SCCM2012SP1.

Are there any other ways to get this going?
