running 2.65 site not working on new 2008 server ( Unrecognized attribute 'targetFramework')

Hi-

I've got a running nopcommerce 2.65 site in development on a Windows 2003 server. I wanted to upgrade my nopcommerce to newer versions, but my server didn't support it. So...I have obtained a new Windows 2008 server and copied my 2.65 site to it. Once running, I planned to follow the procedures for upgrading it to 2.8.

When I try to access it in a browser, I get this error:

-------------------------------------------------------------------------------

I guess this means that my new server doesn't have the older .NET framework installed???
What all has to happen for me to be able to run my site on this server?

Thanks,
Steve

I presume you already have .NET 4.0 or .NET 4.5 installed. Have a look at this page.

Also ensure that that the website is set to use ASP.NET 4.0 and uses that application pool (IIS settings).

Thank you very much!

Indeed..I had not noticed that my site was using the DefaultAppPool, which is using version 2.0 .NET-
