Installing Share Point 2010 on Windows 2008 R2 and Windows 7 Prerequisites


If you will be installing the SharePoint Server 2010 Public Beta on Microsoft Windows Server 2008 R2 or Microsoft Windows 7, then you will need to download and install an update from http://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=23806  to resolve an issue that occurs in Microsoft SharePoint Server 2010 when provisioning Service Applications or when accessing pages that make service calls.  Without the hotfix, these operations will result in an error "System.Configuration.ConfigurationErrorsException: Unrecognized attribute ‘allowInsecureTransport’. Note that attribute names are case-sensitive. (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\WebClients\<Service Area>\client.config line <Line Number>)". 

If you have already installed Microsoft SharePoint Server 2010 on a server running Microsoft Windows Server 2008 R2 or Microsoft Windows 7, Microsoft SharePoint Server 2010 does not need to be reinstalled when the update becomes available; however, Service Applications that have been successfully provisioned without the update installed may need to be removed and re-provisioned once the update has been successfully applied
