WSUS Keeps failing on SCCM 2012 R2

Question

Hello all
I am hoping I could get some help with this strange issue:
I am trying to install WSUS on my sccm server prior to the software update point. This what I have done so far:<o:p></o:p>
 In server manger I select to install the WSUS role>Click next (I notice there is a feature option to install Windows internal database)
I unchecked this option because I am using my existing sql server for the WSUS instance. I cant seem to find anything that say tells me that when installing sccm 2012 on Windows Server 2012 and you are using the sql database instance for WSUS to do xyz. In
my case as mentioned before  unchecked the Windows Internal Database Feature. Then under Roles Services there are three option: WID Database, WSUS Services, Database. I chose WSUS Services and Database. On the next page I defined my source for the downloads,
then the next page DB Instance I entered the instance of the sql server which in my case is also on my sccm 2012 server VMSCCM is the name> Click Check Connection and that was successfully connected to the server. <o:p></o:p>
So here is where everything goes wrong. I then select to install everything at the confirmation page. reboot the server<o:p></o:p>
once rebooted I open server manager and there is message that says Launch post - installation configuration. I then get the following error "Post-deployment
configuration failed see log below is a image for the log located in c:\users\username\appdata\local\temp\tmpFC3D\
<o:p></o:p>
<o:p></o:p>

I had similar issues with the WSUS integration with ConfigMgr 2012 R2. I also have the WSUS DB hosted on the same SQL instance where ConfigMgr 2012 installs it's database.
I found WSUS would not function correctly until I added the SYSTEM account to the WSUS Administrators group under Local Users and Groups:
Hope this helps! :-)

Look under Plan for WSUS Installation heading. You can also add
NT AUTHORITY\SYSTEM account as a user for the WSUS database (SUSDB) and configure a minimum of the webService database role membership as an alternative to the above
Hello again,
How would I add this account. When I go into th WSUS admin group on the local machines I cannot search for the this type of account. It returns nothing.
Thanks
