What happened to old products

I started using Topaz products way back when. One of the early products I used was called Simplify. I have not done much photography stuff lately and I am wondering what happened to Simplify and the other early products. Are they still available?

Simplify and many others are considered Legacy products. That means they are no longer for sale or are being developed. If you already own them and need to reinstall, you will find the downloads here.

Lots of great plug-ins that I still use often.

They were unfortunately discontinued in lieu of the AI products.

Is Any Body having Problems Running Legacy Products ?
I am unable to use Adjust AI on on my I Mac now.
