Question How to change and save Product name using script in play mode (In Editor)

Hello there,
My game has 2 versions, one for the full version and one for the demo. For this reason, I want to change the product name using a script so that I don't forget to change the name before building. I tried this:

Code (CSharp):

1. PlayerSettings.productName = prodName;

But it's not saving permanently, and reverting back to original name once I am exiting play mode.
How to save this change? Or this code is only supposed to run from editor script?

 

... Are you running this during play mode?

Any of this core editor stuff should be done outside of play mode.

 

My first instinct would be to write a custom build pipeline that includes/excludes whatever you want to have in the two versions respectively and names them accordingly.
