If PerfectlyClear plugin has been installed correctly, it will be found from the Edit window, under Effects -> Plugins -> Authentech Imaging
If there is no Plugin listed, I would verify if:
- there is a folder called PerfectlyClearForPSP with the below content:
32 bit: C:\Program Files (x86)\Corel\Corel PaintShop Pro X9\PlugIns\EN
64 bit: C:\Program Files\Corel\Corel PaintShop Pro X9 (64-bit)\PlugIns\EN
2. there is a file called Athentech_PerfectlyClear.exe under C:\Program Files (x86)\Corel\Corel PaintShop Pro X9 Setup Files
If the Athentech_PerfectlyClear.exe exists, double click it to re-run it.
If the Athentech_PerfectlyClear.exe does not exist, I recommend you re-download/install from your download folder or the link provided with your order confirmation.
Once the installation is complete, relaunch PaintShop Pro X9 and go to the Edit window, under Effects -> Plugins -> Authentech Imaging
Your plugin should be visible.
