S7 driver cannot start after upgrade to WinCC OA 3.14 P003

[agruber]

Hello,

One of our customers made us aware that if you upgrade from WinCC OA 3.14 P002 to P003, a DLL is missing.

If you use the S7 driver, you will get an error message about the AGLink_x64.dll .

Also repair does not work in that case.

If you do not use the S7 driver, no action has to be taken.

At the moment the solution is to deinstall the installed version and install P003 standalone (not as upgrade from P002).

Sorry for the inconvenience.

BR,
Andreas Gruber,
