Install multiple versions of Tia portal in a PC

Hello everyone,

I've already had SIMATIC TIA PORTAL STEP 7 PRO + WINCC PRO V16.0 installed on my machine.

I want to install SIMATIC TIA PORTAL STEP 7 PRO V15.1 on my machine but most of the setup files on the internet include both Tia portal and WinCC pro, so when I get the error:

tia portal step 7 pro v15.1 - winCC professional v15.1 cannot be operated in parallel with the currently installed version of "winCC professional" or "WinCC Runtime professional"

 As a result, I am unable to install TIA PORTAL V15.1.

Can anyone help me?

Thanks and regards.
