    If the instance is not available, we recommend re-installing WinCC.

  • Make sure that the version number of the SQL Server is identical on both computers (see "SQL Server ..." in Fig. 1).

  • Make sure that the same version of WinCC (including Hotfix/Update) is installed on WinCC/PCS 7 ES and WinCC/PCS 7 OS.

  • If you are working with Windows Vista, Windows 7 or Windows Server 2008 on the ES, make sure that the user account control (UAC) is disabled.
    You disable the user account control in Windows 7 by going to "Start > Control Panel > System and Security > User Account Control Settings".
    Select the lowest slider setting.
