how to change substance painter steam license to stand alone license?

Hi everyone, I was wondering is there a way to convert a substance painter steam license to a stand alone license like before. I can remember that there was a way to link the license from the substance 3d site to the steam version. But unfortunatelly it doesn't work anymore. How can I convert my license to a standalone version?.  Any help is highly appreciated 🙂 

thanks in advance
