After purchase, a dialogue box indicated that I just needed to input my licence key and it would be ready use. Which it was but I had a few probs so I had to uninstall it and reinstall it. This time I used the exe that was available through my email that confirmed the purchase.
I was so pleased I did, as I would have failed to note that firstly, this exe file was almost 1 GB larger than the exe for the trial version, and secondly, the final product it downloaded was 2GB larger, of which PaintShop Pro 2021 is included along with others (from memory) 5 plugins.
So, I guess I was lucky to have problems with this as I would have not realised otherwise, and just posting this to let you know in case it applies to you but you’re not aware of it.
Thanks
