Need help setting up ASP.net 3.5 (Screenshots)

This is driving me crazy, and has been bugging me for weeks, I'm trying to sort it all out today but am having real difficulty, if anyone could help it would be a HUGE benefit to me!

I'm trying to get a website I've developed on one computer, to work on my home computer. The old computer was running ASP.net 3.5.

On my new computer, after installing IIS and ASP.net 3.5:

I get the following error:

Upon checking the application pool, it says it is running ASP.net 2.0:

And there is no option to change it to 3.5:

I've checked regedit for the installed .net versions and 3.5 is listed there as installed. I just can't seem to get my site to run with 3.5, or run at all without any strange IIS error messages.

This thread: http://forums.asp.net/p/1184937/2018939.aspx suggests that 2.0 showing is correct, my issue then is why is the site not running?

Here is my web.config file:

And here is my applicationHost.config: http://pastebin.com/m3nYmn4n

Thank you so much for any help, fat juicy bounty on it's way when I can.

Try aspnet_regiis from the framework 3.5 if you have installed IIS after .NET framework.

By the way, I cannot see your images for some reason (I am behind firewall)

There is no ".NET Framework version" for 3.5, 3.5 is just a collection of libraries that run on .NET Framework 2.0, so what you've got there is correct.

Is "C:\Projects\AlphaPack\AlphaPack" set up as an Application in IIS? The <handlers> configuration element can only be set in the root web.config of the application, so my guess is that you've just set up the directory as a virtual directory and not as an Application.

What is in the directory alongside the .config file? Are all of your website pages/ resources in the directory below this file? The physical path to the site is one directory further down than the location of the .config, or so it seems, which could potentially be an issue.
