Hi,

My system is windows11 21H2. And the TIA Portal version is TIAV16.UPD5.

When I click the start simulate button try to start WinCC. The Compile window show "Compiling finished(errors:0;warnings:0). But the WinCC does not start. Only show a Compile message.No other action. 

What should I do to fix this problem?

 Hello, After I click the start Simulate button.

please can you add some screens what exactyl is displayed/You see?

 Hello, Thank you for your attention.I have updated a photo. 

ChristophD

and what is displayed in the yello flagged General tab?

ChristophD

please click on the yellow triangel in the last sxcreen so that all messages are displayed.

the actuall settings hide some warning messages.

Also no other message.  I'm very confused about this. Maybe after clicking the button. the project does not compile.

you must restart the steps for simulating again after deactivation of this messagefilter

 I restart my computer. And open the project. start to simulate. it's the same. no other message. If you are concerned about the yellow "!" in the first photo. When I open the project. the default window is in Compile. And the General tap shows a yellow "!". when I click the tap, General. No message in the window.
