WinCC OA 3.15 - crash Excel report in 3.14

[MrKintaro]

be careful to install the 3.15 in a machine where there is a 3.14 installed.

We tried the Excel report of the 3.14 after the installation of 3.15 and the excel was crashing but in 3.15 was working.

We remove the 3.15 and the 3.14 report was saying that the Excel has no complements.

we are trying to repair 3.14, I will keep you inform.

The reason for this is that the COM Manager exists only once per Windows operating system as it gets registered in the Windows registry.

So once you have installed 3.15 the 3.15 COM manager tries to connect to the 3.14 project which does not work and results in this behavior you describe.

You should be able to register the COM manager for Excel Report by opening a command shell as administrator and execute the command:

Code: Select all

C:\\Windows\\SysWOW64\\regsvr32.exe C:\\Siemens\\Automation\\WinCC_OA\\3.14\\bin\\windows\\WCCOAcom.dll

You can can switch back to the 3.15 COM manager by executing the command with the 3.15 dll.
