Today we have started getting this error when we try to open SQL Server 2014 Management Studio.The install was done using the correct media with the appropriate product key.
I have:
- Gone through the process of an Edition Upgrade on all my Instances and Shared Features
- Uninstalled Shared Features and reinstalled.
- Tried editing the registry key, CommonFiles from 1 to 3 underHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\120\ConfigurationState (120 as this is an install of SQL 2014). I have also tried switching this back to 1 and re-running the Upgrade.
I have rebooted the server several times but I am still not able to open the Management Studio.
I notice this was an issue in 2008 but I cannot find any fixes for 2014.
Thanks.
