Anyone else getting Windows Insider builds of Win11 and trying to use Painter 2022? I have this on my Surface Book 2 and noticed that I can no longer run the Brush Accelerator. When I start it the document window that Brush Accelerator paints on pops up and then immediately closes without running through the performance test. I previously had P2022 running on this same laptop with Windows 10 and got the accelerator to run so I'm assuming it's something with Win11.
Solved by resetting Corel Painter by holding down shift while starting to get the Painter factory reset dialog. Then I reset All the settings and on restart the brush accelerator ran fine.
Background is I had a trial of Corel Painter 2022 installed while the machine was on Win 10. Then I started to receive Windows Insider builds of Win 11. When I activated Painter with my purchased license I couldn't re-run the brush accelerator. Only with a full Painter reset would the accelerator work again.
Not working for me either. I tried your method and still couldn't get it to work.
