Win7 SP1 slipstream option does not exist

[cess]

Hello,

I installed RT7 Lite latest version. I download latest SP1 from MS site yesterday. Its "windows6.1-KB976932-X64"

Installed Win7 Home Premium x64

There is no "Slipstream service pack" option or checkbox on OS image selection window.

Whats wrong?

Thanks in advance

AFAIK, you need to have Beta build 2.5.0, which includes the option to slipstream service packs.
