PaintShop Pro 2019 included Perfectly Clear 3.5 SE, which doesn’t work with PaintShop Pro 2020. But we’ve replaced Perfectly Clear with the Corel version of GRFX Studio, which can be found in Effects > Plugins > AutoFX Software.
If you want to continue working with Perfectly Clear, you can purchase the full version, which contains more features than the version included with PaintShop Pro 2019. To find this version, go to the Welcome Book, click Get More, filter the list to show Plugins, and purchase Perfectly Clear Complete 3.
