Error code when trying to install Microsoft Security Essentials on Windows 7

When I try to install Security Essentials on a new HP desktop with Windows 7, I get error code 0x80070643.

I looked this up and found where Microsoft Installer might not be turned on.  I checked, however, and Installer is indeed on.

Any solution to getting Security Essentials to install?
