Deploying Office 2013 ProPlus using SCCM, making it prompt for restart! Help?

Hello all,

I am trying to find the right combination of Microsoft Office Customization Tool to deploy Office 2013 ProPlus using our SCCM environment, but where it will not forcefully restart the computer but prompt the user to reboot.  

Can anyone help?   

I have used the following two Setup Properties to customize my install, which should make it prompt for reboot but it does not...it forces a restart as soon as it completes:

SETUP_REBOOT    - Value IfNeeded

also, I put in HIDEUPDATEUI - value true to hide this annoyance from my users. 

I push it out through sccm 2012 and it does its thing and installs correctly, but then forces a reboot. 

What am I doing wrong, I know it's something very simple.  

Any help is greatly appreciated!
