I'm a new employee here, and I am trying to use Sitefinity locally so I can get up to speed on the software. I can create a new project, but then when I try to launch the project by double-clicking on the location, I get an error:

FileNotFoundException
Cold not load file or assembly 'System.Web, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=xxxxxxxxxxxxx' or one of its dependencies. The system cannot find the file specified.

I have installed the latest 4.4 version of Sitefinity on an older temporary laptop that belonged to several people prior to me, so I'm not sure what is already on this computer. Any ideas?

Hi Bill,

Can you make sure that you have installed .NET on your machine, on which you are running Sitefinity and if you have verify that the application pool which is used by Sitefinity is .NET 4 app pool. In the meantime you can also check our system requirements page:

Not having .net 4 installed was the problem. Thanks.
