I am trying to install update rollup 2 for CRM 4.0
However it fails with error
Action Microsoft.Crm.UpdateWrapper.MspInstallAction failed.The installation source for this product is not available. Verify that the source exists and that you can access it.
Here is some of the log file where it fails.16:14:36|Verbose| Method entry: Microsoft.Crm.UpdateWrapper.UpdateSetup.Install| System.Collections.Hashtable
