Vista Service Pack 2 will not install

I have Vista Business on a Lenovo T61 Laptop with SP1 installed. It came with it on it. I downloaded SP2 successfully, but it won't install. It tells me to install SP1 first. So, I downloaded SP1, and it wouldn't install because it's already installed! It's a Catch 22. It just goes round in circles. Get me out of this loop!

I do have screen captures of the error messages I get, if anyone is interested

Hi Bobdown,
Thank you for visiting Microsoft Answers forum.
Try running the System Update Readiness tool prior to installing SP1 or SP2.
