How can you install WinCC while the computer is logged on to a domain?

  • Entry
  • Associated product(s)

In SIMATIC WinCC, it is not possible to do an installation of WinCC while the computer is logged on to a domain.


  • Log on locally with administrator rights to the computer in question. An installation under the Microsoft Windows operating system requires administrator rights.
  • Refer to the requirements for installation in the SIMATIC WinCC Installation Notes or in the relevant section of the WinCC Information System. 
  • Once the installation is finished, you can log on to the domain again as usual.

More information regarding the use of WinCC systems on a domain is available in the WinCC Information System under the keyword "Domain".
Information on the installation of WinCC can be found in the WinCC Information System under "Installation Notes > Requirements for Installation".
