I've become dumber than ever????

I've reinstalled twice my licensed S&D and I can't see the option to Install Security Center Integration, neither at install time nor under "System Services" in settings...

I've even been unable to locate the executable files for integration under the install folder (so I can't even run "by hand")

BTW, I'm logged with Administrator privileges.

I've googled a lot and searched into the forum, but I only find ways to uninstall.
My problem is the other way round...

Can you please help me?
