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... 

I need help on the best way to just "RUNONCE" any help would be greatly appreciated.

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
