Hi, We have a deployment package, which gets deployed in test server farm environment(2 WEFs, 1 App Server, 1 SQL Server) but the same package fails to get deployed in production environment with similar server farm. It throws the error saying that "Error: Cannot add the specified assembly to the global assembly cache" inapplication server. But itsuccessfully gets deployed in 2 WFEs servers of production env. The only difference between test and production env is, in production the central admin is configured in app server but in test server farm its there in one of the WFE. The SharePoint log shows the following error: 09/21/2009 14:31:25.02 OWSTIMER.EXE (0x0680) 0x06C4 Windows SharePoint Services Timer 6759 Critical The Execute method of job definition "SPSolutionDeploymentJobDefinition" (id "695a3e94-969a-430f-94db-10836c9b0d55") threw an exception. Error: Cannot add the specified assembly to the global assembly cache: GAC\SomeWebPart.dll. What could be the issue here? Thanks, San

Hi Aseem ..Thanks for your responding to this ..We are using the SharePoint Administrator screen to deploy the solution,and already get an alert about the GAC deployment in that screen. So I hope thats not an issue. Also the same package is getting deployed successfully on test server farm with similar farm environment as production.

Hi Please be sure that youre running as both a local administrator on the server and an administrator within the SharePoint farm. Does this issue disappear after the server is rebooted?If so, the reason for this might be that the SharePoint application pool service account did not have appropriate permission to activate IIS REGWAM admin service. You can walk through it by explicitly adding these permissions in the DCOM management console and then restarting IIS and Windows SharePoint Timer Service. Best Regards!

Hi Lily, So, you are saying FARM ADMINISTRATOR ACCOUNT should also have local administrator access. Can you please tell me then what's the diferrence between the INSTALL ACCOUNT and FARM ADMINISTRATOR account? Best Regards! Jas
