Silverlight isn't installing properly?

I've been using Silverlight since I got my grubby hands on it day #2 of Microsoft. In light of this for some reason I noticed that Silverlight Alpha 1.1 wouldn't install properly on one of my machines.

After a few "Did you uninstall version 1.0? " style responses to my questions and a few random thoughts floating around inside my head like ("No you damn idiot, it didn't occur to me to uninstall the previous version to make way for the 1.1 version.. ") I did stumble upon this blog post.

(The funny part was that I actually subscribe the RSS feeds for this blog and just goes to show how much I pay attention at times to blogs I read).

This post outlines the counter-act around my issue and while you shouldn't screw with the registry unless you know what you are doing (translation: you once screwed around inside the registry and your computers app's stopped working and you came to the sad realization that you made a mistake - CANCEL or ACCEPT).

Hey, it's alpha folks so keep calm and relax.
