Hello all,

As the title states, I'm having issues inside Siemens TIA Portal V18 trying to simulate the HMI screen with PLC Simulator. The "Start Simulation" button in TIA portal stays grayed out and does not allow me to click it. This is only the case though for unified panels, as I can successfully simulate non-unified panels. The only thing I have found on Siemens' website lists the file SIMATIC WinCC Unified RT PC V18 Simulation & Trial as required for simulating WinCC Unified Comfort with TIA portals V18, but when I try to install this, I get the error it cannot run in parallel with my currently installed software.

Am I missing something simple here, or is there a bigger issue not allowing me to simulate Unified Comfort panels inside of TIA Portal V18?
