License Keys:

• The Server Install requires a license key. Trial license keys have been provided on this page.
• Information regarding the availability of non-trial keys will be forthcoming from our marketing team.
• IMPORTANT! You may use the Microsoft Dynamics CRM 4.0 editions with the respective License Keys for a maximum of 90 days. Each edition may be converted to a full use version by applying a commercial license key in the Microsoft CRM License Manager. A re-install of the software is not required. You will need to convert the license key to a commercial license before the 90-day period ends, as the 90 day period cannot be extended, and Users will not be warned of the impending expiration. Should expiration occur, access can be regained by applying a commercial license key.

Build Number:

• The final build number was 4.0.7333.3
• If you were involved in the pre-release programs please make sure that you clean up all your old DLLs for older versions.
• You will want to recompile any code against the RTM Microsoft.Crm.Sdk.dll and Microsoft.Crm.SdkTypeProxy.dll. These two assemblies can be found in the GAC folder of the Server Install.
• If you use a static copy of the Discovery Service (like I do) you should also grab a new copy of this. Remember that the WSDL for the discovery service is interchangeable between WLID, Windows and IFD authentication end-points.
