Remove the following assemblies from GAC. Path for the GAC: c:\Windows\assembly

• Microsoft.Dynamics.Framework.Portal and all the resource DLLs
•  Microsoft.Dynamics.Framework.Portal.CommonControls
• Microsoft.Dynamics.WebParts and all the resource DLL

Install the AxWebParts.cab solution from either of the following.

•   Ax Setup install Enterprise Portal and Roles Center
•  Go to Sharepoint Central Administration –> Operations Management-> Solutions Management, check if axwebpart.cab is present and “Error” is displayed against it. Deploy the solution from here directly, this will save some time instead of running Ax Setup and waiting for installation of complete EP Site.
