Deploying MS Office 2013 with GPO

Question

OK i would like to deploy office 2013 via GPO, i finally have been able to get the script to work however there is one more detail i need to get figured out.... How can i incorporate into the script so that it will only run once...  my script is below
and does the following, it uninstalls office 2010 whether it be 32bit or 64bit then silently installs office 2013 as a startup GPO... how would the script look if i'd like to add so that it looks for a specific txt file that if its there it does nothing and
if it's not it runs install script and perhaps at end of install script maybe it creates that txt file... I need help on the best way to just "RUNONCE"
here is my script:
"C:\Program Files\Common Files\Microsoft Shared\OFFICE14\Office Setup Controller\setup.exe" /uninstall ProPlus /config "\\****\Office13\Uni_Office_10\SilentUninstall.xml"
"C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE14\Office Setup Controller\setup.exe" /uninstall ProPlus /config "\\****\Office13\Uni_Office_10\SilentUninstall.xml"
setlocal

if NOT %errorlevel%==1 (goto End)
REM Check for 32 and 64 bit versions of Office 2010 in regular uninstall key.(Office 64bit would also appear here on a 64bit OS)
:ARP86
reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall%ProductName%
if %errorlevel%==1 (goto DeployOffice) else (goto End)
REM If 1 returned, the product was not found. Run setup here.

echo %date% %time% %computername% Setup ended with error code %errorlevel%. >> %LogLocation%\FinishedInstall.txt
REM If 0 or other was returned, the product was found or another error occurred. Do nothing.

The problem with Office 2010 and later is that it is not designed to be installed remotely or by a script. You need to create an install spec and set up some prerequisites fist.  If you ten follow the instructions for using a GPO to deploy Office
you will not need to  use a "RunOnce" key or anything else.
Note that eh RunOnce key take a command or batch and command and is deleted as soon as it is executed.  The problem you have to solve is how to set the RunOnce key to begin with.
You really must use the information in the links posted for Office deployment.  You cannot do an end run around this with any success.  If you search for forum posts on this you will see that many have been exactly where you are.  Don't wast
your time.  Follow the instructions as posted in the Office forum and on the TechNet link.  YOu will find it is actually quite easy and very flexible once you understand the steps.
