I'm new, so this may be a stupid question.
I have Vista Home Premium x32 that's already VLited. The problem is that there is no Service Pack 1 installed. I can't install it the regular way because I get the 0x80070002 error. My question is how do you get Service Pack 1 after your Vista is already VLited? Is it too late at this point?

You can't install Service Pack 1 on vlited Vista.....vlite removes some dependency binaries....that why you can't..

So you have to slipstream SP1 and then try to lite Vista.
