Install Error - No MediaTypeFormatter is available to read an object
I have installed UmbracoCMS through Visual Studio 2013 NuGet. The project builds fine, but when I run the project in the browser, and begin the install process I get this error, has anyone seen this problem and have a fix for it?
Error during installation
No MediaTypeFormatter is available to read an object of type
'IEnumerable`1' from content with media type 'text/html'.
See the log for full details (logs can typically be found in the
App_Data\Logs folder).
I have checked the Logs and the details are as follows:

I also come across this problem. Does anyone have a good solution for it ?
Hi Andy, I get the same - did you manage to solve it?
Is this related to a network problem? Had the same thing and I think it was down to the client site firewall.
Hi everyone! I also encountered this error and I can't still continue to install Umbraco. Can someone help me?
Hi all, were you able to figure out what needed to be done with this error?
