Windows Local Administrator account to push SEP.

I have noticed that SEP will NOT install unless the local administrator account is enabled. Here is the problem, we do NOT want to enabled the local account "Administrator" it is a security issue. We want to rename our Administrator account and NOT have to have SEP depend on "Administrator" for installation.

So, let's say, I want to rename the Administrator account "chuck" How can I get SEP to deploy with the "Administrator" account named "chuck" or does it HAVE to be installed using "Administrator"

Windows 2003/2008 Server, 32/64 Bit and Windows 7 64 Bit and Windows 32 Bit XP Systems.
