I am installing TIA Portal, I have installed V11 and v12 (lastest versions) but, when I am trying to install WinCC Professional V13 i am getting a error.
"WinCC Professional V13.0 cannot be operated in parallel with the currently installed versión of WinnCC Professional or WinCC Runtime Professional.
Please remove WinCC Professional and WinCC Runtime Professional in order to opérate WinCC Profesional V13."
In another PC, I have installed V11, v12, v13 WinCC Comfort/advanced.
Is it not posible to have both versions in the same PC?
Thanks in advance
