Since I upgraded to OS Catalina, I cannot open my Print Shop 3 app, Version 6.2.10.0. How do I upgrade it to run with Catalina?

If you read the fine print it says it’s not available in North America. Why? I don’t have a clue.

No idea why, but I went to the vendor’s website, indicated I lived in another country and got the downloadlink immediately
