Okay, so I'm trying my damndest to install Visual Studio , and every time I get part-way through the installation process, it comes up with an error saying it can't find some random .cab file, which I know is freaking there because I'm looking right at it, and the installer should be too, because I checked the path. Anyway, it won't get past that point in installation, EVER.

On top of that, I just upgraded from XP Home to XP Pro (yes, I know I'm lazy, but that's not the point) and my updates won't install automatically. I have to search through and install them manually from Microsoft's Download Center. It's becoming a real pain.

Has anyone else experienced and/or resolved this or a similar issue?
