The Toolkit General Discussion

Hello there,
i wrote a script with PSAPPDEP to change the default XML file for Symantec EPP to our´s but this makes a problem.

if i run my script as local Admin it´s run fine and there comes no error and the file would be change.

if i run the script with SYSTEM Credential, also as CM12, the script runs into error and said the folder is locked.

here now the part of my script.

		##* INSTALLATION

		[string]$installPhase = 'Installation'
		
		## Handle Zero-Config MSI Installations
		If ($useDefaultMsi) { Execute-MSI -Action 'Install' -Path $defaultMsiFile }
		
		## <Perform Installation tasks here>
		$client = Get-childitem env:computername 
		#$strFileName = ${env:ProgramFiles(x86)} + '\Symantec\Symantec Endpoint Protection\Smc.exe'
		#$strFileName1 = ${env:ProgramData} + '\Symantec\Symantec Endpoint Protection\CurrentVersion\Data\Config'
		$REGKEYSYMANTEC0 = Get-ItemProperty -path "HKLM:\SYSTEM\CurrentControlSet\services\SysPlant"
		$REGKEYSYMANTEC1 = $REGKEYSYMANTEC0.ConfigDatDir + 'SyLink.xml'
		
		Execute-Process -Path "CMD.EXE" -Parameters '/C start smc.exe -stop' -WindowStyle Hidden
		Start-Sleep 10
		If ($client -Match "NTB*") { Copy-File -Path "$dirFiles\GER_W7_ID-W7_Laptops_sylink.xml" -Destination "$REGKEYSYMANTEC1" -Recurse }
		If ($client -Match "WKS*") { Copy-File -Path "$dirFiles\GER_W7_ID-W7_Desktops_sylink.xml" -Destination "$REGKEYSYMANTEC1" -Recurse }
		If ($client -Match "WAE*") { Copy-File -Path "$dirFiles\GER_W7_ID-W7_Desktops_sylink.xml" -Destination "$REGKEYSYMANTEC1" -Recurse }
		Start-Sleep 5
		Execute-Process -Path "CMD.EXE" -Parameters '/C start smc.exe -start' -WindowStyle Hidden
		Start-Sleep 10
