WinCC interface and 64-bit operating system
The public
interface of WinCC offer no native 64-bit support. This primarily affects ODK, VBS
and the WinCC OLEDB provider. To use the interface of WinCC under a 64-bit operating
system, you must adhere to the following:
● You cannot launch VB scripts simply with a double-click. You must explicitly use the 32-bit
version under "syswow64\wscript.exe".
● .NET applications that use the WinCC API must be explicitly compiles as 32-bit applications.
With "x86" and not with "AnyCPU".
● C++ applications cannot be compiled as 64-bit applications.
Preventing access to Windows in runtime
Displaying the online help in runtime
If you wish to ensure that operators have no access to the operating system level of a plant,
deactivate online help in all controls. This prevents the Windows selection dialog from opening.
Deactivate the "Help available during runtime" option in the "Project properties" dialog in the
"Options" tab.
Displaying the Windows taskbar in runtime
You can use the computer properties to prevent the Windows taskbar from being displayed in
runtime. Open the "Parameters" tab in the "Computer properties" dialog and disable the option
"Disable shortcut keys for operating system access" in the "Disable Keys" area.
In addition, deactivate the "Keep the taskbar on top of other windows" setting in Windows.
