Dear Stefan ,

Where to find the PC Runtime version?

Here is some information.

Unifed V20 and V19 upd3  (ES and RT) are installed paralleled on my computer. They are running fine.

After I installed PC Runtime V20, I can't find PC Runtime V19 upd3 on my computer.

Also in "installed software component" and "Windows10 installed software", I can't find V19 upd3.

Runtime Manager V20

I check my instance in Runtime Manager V20, It seems i can see V19upd3's instance.

My Question

Where is Unified RT v19 upd3 installed. Does it overwrite by RT Unified V20 ?

Hi Kethan,

Here are some recommendations:

• Check if an update is available for your software, especially for WinCC Unified PC Runtime.
• Delete all projects from the SIMATIC Runtime Manager and then try to start the simulation.

If this does not help, please provide more information:

• What is your engineering version?
• Which version of WinCC Unified PC Runtime are you using?
• Which device version is configured in the project?
• What does the SIMATIC Runtime Manager show?

Kind regards
Stefan
