Hello experts,

I'm really in trouble having Wincc RT Professional running on my computer. It has consistently come with an error "Compilation not possible. the "WinCC" SQL instance is either not running or not available" anytime I compile it. I searched that it dues to SQL server (WINCC) is not running so I was gonna enable it in Sql server configuration manager but it didn't have such thing like that in the list of SQL Server services. How can I add it or make Wincc Pro run successfully? I'm using TIA Portal V14 that worked well with Wincc RT Advanced and the SIMATIC WinCC Runtime Professional has also installed formerly. Hope this description enough and clear for you. Any help would be appreciated.

Hi, other services are still running normally
