Hi
We were trying to upgrade our server from SQL Server 2008 R2 to 2012 enterprise edition. During Upgrade I got the attached error. While researching on this error, I was checking the registry as well and I found a path there which was not there on our server. I created the required folders and then I clicked ok on the attached error message. The upgrade then moved ahead fine and completed successfully.
I then restarted the SQL Server Service. But I still see the old version of SQL server on this machine. I am not sure why it didn't get updgraded.
I also checked the error logs and event viewer and found the below error:
2016-11-24 11:24:48.090spid8sSQL Server failed to set security information on the full-text FilterData directory in the FTData folder. Full-text indexing of some types of documents may fail until this issue is resolved. You will need to repair the SQL Server installation
