Commented Issue: Crawl log error: "The filtering process has been terminated" [18863]

Using AutoSPInstaller and SharePoint 2013 on a Windows 2008 R2.
When you choose to put index in a non default location i.e. D:\SharePointIndex the above error occurs.
I've looked into it and when not using default "-rootdirectory" WSS_WPG group don't get correct permissions on
C:\Program Files\Microsoft Office Servers\15.0\Data\Office Server\Applications.
It should have "Full Control"

Is there a PowerShell script to correct this issue?. if so please post it here.
Thanks
