Language of the Setup Wizard

If you start the WinCC OA installation through WinCC_OA_3.20_Setup_x64.exe, the installation language depends on the language that was set via the control panel. First the "User locale" language is used if it was configured. You can set the "User locale" via Control Panel > Region and Language > Formats tab > Format.

If the "User locale" language was not set, the "System locale" language is used. Set the "System locale" via Control Panel > Region and Language > Administrative tab Click the Change system locale... button. This means that if a language was set for a user, this language is used. If a user language was not set, the system language is used.

If neither "User" nor "System" language was specified, English is used. If you install an update, the language of the original version installation is used by default. The WinCC_OA_3.20_Setup_x64.exe can also be called by using a language option directly.

You can call the setup by using a language option directly.

Setup call in English:

WinCC_OA_3.20_Setup_x64.exe /lang en

Restriction: Note that if the installation was executed in one language, e.g.: in German, you have to uninstall WinCC OA to execute the installation in another language, e.g.: English.

Important: If the error "Error 1324. The path Datenpunkttypen_f?_Symbolkatalog contains an invalid character." occurs during the installation of WinCC OA, the settings for programs that do not support Unicode must be changed. Under Control Panel > Regional and Language Options > Advanced the option Select a language to match the language version of the non-Unicode programs you want to use must be set to either German or English.
