Why Do I get different result when Run as Admin to Standard?

Question

Why when Running this script to copy from the "config64" folder (if files exist)(if not copy from "config32")  if works correctly when running  Batch file normally (copies the config64), but using the exact same line when running
the Batch file as "Run as Administrator" it doesn't work correctly (copies the config32, even though Files do exist config64 folder as they did when I ran it normally and it worked)
>nul 2>nul dir /a-d "Folder\config64\*" /s && (XCOPY "%~dp0Folder\config64\File64.ini" "%ProgramFiles(x86)%\CompanyFolder\ProductFolder\" /y /d) || (XCOPY "%~dp0Folder\config32\File32.ini" "%ProgramFiles(x86)%\CompanyFolder\ProductFolder\" /y /d)
UAC is turned off and I'm the administrator (only user on a standalone PC) running windows 8.1.
Is there a reason or it is a strange bug with Windows 8.1?

A LOT  more intellectual than
Frederik Long Who just had no clue himself to not offer an answer. As I've only been looking at this for 2 weeks I think I've come far and you help is much appreciated. Thank you JRV!
You seem to miss the point. Assuming that your problem is caused by a bug can prevent you from finding the real cause. If you had dismissed the bug theory then you might have done some real debugging, e.g. by breaking up your single-line script (which is
hard to comprehend) into easily digestible pieces and adding some debugging code like so:
@echo off
set Target="%ProgramFiles(x86)%\ComapanyFolder\ProductFolder\"
dir /a-d "Folder\config64\*" /s 1>c:\Test.log 2>&1
if %ErrorLevel% EQU 0 (
XCOPY "%~dp0Folder\config64\File64.ini" %Target% /y /d /s 1>>c:\Test.log 2>>&1
) else (
XCOPY "%~dp0Folder\config32\File32.ini" %Target% /y /d /s 1>>c:\Test.log 2>>&1
The log file would have told you quickly what is going on. Furthermore - why should I offer my own solution to your problem when JRV gave you a perfect answer straight away?
