I try to install SharePoint 2010 on Windows 8.

There is a problem on step 7 of Configuration Wizard:

11/04/2012 19:12:28 8 ERR Failed to provision the SharePoint Central Administration Web Application. An exception of type System.Runtime.InteropServices.COMException was thrown. Additional exception information: Filename: \?\C:\inetpub\wwwroot\wss\VirtualDirectories\34108\web.config Line number: 25 Error: Defined copy of the partition "system.web.extensions/scripting/scriptResourceHandler"

System.Runtime.InteropServices.COMException (0x800700B7): Filename: \?\C:\inetpub\wwwroot\wss\VirtualDirectories\34108\web.config Line number: 25 Error: Defined copy of the partition "system.web.extensions/scripting/scriptResourceHandler"

What's wrong?

Max, check the version of .NET you have installed. Sharepoint 2010 requires .NET 3.5 and does not support 4.0.

"SharePoint 2010 does not support access from .NET Framework 4 or being run in a .NET Framework 4 app domain. If you must support the .NET Framework 4, we recommend that you develop a web service that uses the .NET Framework 4 and then connect to it from SharePoint. All server-side customizations directly for SharePoint 2010 still need to be either the .NET Framework 3.5 or the .NET Framework 3.5 SP1."

In my environment, the root cause is the SharePoing Web service has no permission to execute the Central Admin web application creation.
To solve this error I used the following method.

  1. Clear the cache by opening drive:\ProgramData\Microsoft\SharePoint\Config\Guid and then delete all XML file and open cache.ini, then set the number to 1

  2. open IIS and go to SharePoint Web Services, right click add permissions

  3. add the domain user (I used domain admin) and grant full control

  4. retrun the SharePoint wizard & finish the wizard

Hope it helps ;)
