uninstall 3.15 if 3.16 is running

Post by johanningmann » Wed Aug 14, 2019 6:13 am

Hi, I have a question. We just upgrade from 3.15 to 3.16 and I would like to know if just can uninstall Version 3.15 if 3.16 is running. Or do we have to expect some difficulties?

Kind regards

To be on the safe side you should stop all WinCC OA processes before doing an installation or uninstallation of WinCC OA.
It might work that you do an uninstall of 3.15 while 3.16 is running.

Sometimes (on Windows systems) it might be necessary to reboot the system after an uninstall of WinCC OA which forces you stop the running processes.
