I just spent good hour investigating why YAF_DNN5_1.95.0-4140 keeps throwing error and failing installation

Quote:

Failure Exception - Object reference not set to an instance of an object.
Failure Installation Failed - Config

Then I found that in web.config there isn't child under , so I added it manually and then installation went flawlessly. I wonder whats causing this as I take it installs for everyone else? Anyway I just wanted to leave hint for anyone encountering same problem.

In the default web.config there is a child

<controls>
        <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      </controls>

I thinks that why no one else gets that error

Ah I see, then it must be related to upgrading to .NET 4.0 I did use Microsoft way using Visual Studio to upgrade to fully compatible web.config. Guess these controls are implicit now thus he deleted entire tag.
