    500 Internal Error : Installing Umbraco 7 - win8, iis8

    Hi Guys

     

    After installing umbraco 7 manually, and when redirecting to the backoffice I get a blank page and that erro comes up in the console with a link to this location - mysite/umbraco/Application. When navigating to that location I get the following error.

     

    Method not found: 'System.Collections.Generic.IEnumerator`1<Newtonsoft.Json.Linq.JToken> Newtonsoft.Json.Linq.JArray.GetEnumerator()'.

     

    Help will be greatly appreciated.

    Make sure to get the newest version of json.net in your bin folder. It ships with Umbraco 7, if you installed through NuGet then delete the newtonsoft.json.dll in your bin folder and build your project again in Visual Studio to get the latest version copied in.

    Please report back to let us know if the problem is fixed, thanks!

    Hi!

    I also had this issue. For me it turned out to be an old version of the newtonsoft.json.dll beeing used by the GAC. When i replaced it with the latest version it works fine. On my Win 8 the file was at:

    C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Newtonsoft.Json\v4.0_4.5.0.0__30ad4fe6b2a6aeed\
