SOLVED : Error when starting installation

Hi, I have only just downloaded nopCommerce v1.90 and am trying to start the install process. I have placed the files on my IIS 7 server under nopcomm19.local. Now when I browse to www.nopcomm19.local/install/install.aspx I get the following error:

Server Error in '/' Application.

Configuration Error

Version Information: Microsoft .NET Framework Version:2.0.50727.4211; ASP.NET Version:2.0.50727.4209

I'm only just learning web development so am not sure what this means exactly, but I'll take a guess at having the wrong version of the .NET Framework installed?

According to Control Panel I have .NET Framework 3.5 SP1, .NET Framework 4.0 Client Profile, .NET Framework 4.0 Extended and .NET Framework 4.0 Multi-targeting Pack installed.

Thanks in Advance

Is 4.0 installed and configured?

I'm pretty sure it is as I only recently installed all of the Microsoft Web packages WebPI, WebMatrix etc.

I have actually managed to install nopCommerce now by getting it from the Microsoft website and installing using the Web Platform Installer, went very smoothly doing it that way.

Thanks
