you have a newer version installed.

so use wincc co mfort v14 sp1 for installation.

Hello candemirhalil

In TIA V14 there was a seperate setup for WinCC and Step7.

If you have installed WinCC Basic already then it could be that you have to unistall this part before installing the WinCC Comfort/Advanced.

so open installed Softare in Windows and select TIA Portal -> then do an uninstall -> A dialog pops up where you could unselect the WinCC package. then only WinCC will be uninstalled from TIA Portal.

After that do a restart and use the mentioned V14SP1 Setup for WinCC Comfort/advanced

Then everything should run (do not forget to install the latest Update for TIA V14 SP1 after all)
