WinCC RT Professional V18.

mushbaig Posts: 1 Rating: (0)	I am experiencing an issue with WinCC RT Professional V18. When I attempt to open the runtime project, access is denied by the SQL Server. I am uncertain where to begin troubleshooting this error. "Microsoft SQL Server cannot access the database, please check the access rights"

If yes check if it is member of the local User groups "SIMATIC HMI" and "Siemens TIA Engineer" Check with another project does it work with this? If only one project has the problems try this: https://support.industry.siemens.com/cs/de/en/view/109780381 Bye Murof
