Painter 2020 won't start - Windows blue wheel spins but nothing else happens

Hi, I'm pulling my hair out trying to solve this issue and could use all the help I can get.

I have been a longtime user of PainterX3 and wanted to try 2020 before I bought it.  I downloaded 2020, installed it as a limited-time trial without a serial number, and the installation seemed to go OK.  I didn't get any kind of confirmation when the installation process completed, the screen just closed.

A Painter 2020 icon appeared in my Windows 10 start menu, so I double clicked that.  The Win10 blue wheel appeared for 3-5 seconds, and then disappeared.  Nothing happened.  The application didn't open.  No pop-up screen, no error message, nothing.  I opened the Windows Task Manager to see if I could see Painter spinning up in memory, but nothing, no processes associated with Painter 2020.

I then began a dizzying array of troubleshooting steps...

I cleared the temp folders and held down the Shift key while starting the application.  As before, the Win10 blue wheel spun for 3-5 seconds and then closed.  The app didn't open.

I then uninstalled Painter 2020, ran CCleaner to clean my registry, restarted my computer, and reinstalled Painter2020.  The installation process ran as before, and I could not open the app using either the normal method or by holding down the Shift key while opening the application.

I then uninstalled Painter 2020 a second time, ran CCleaner to clean my registry, and rebooted my computer.  Thinking perhaps I had a bad install file, I deleted the installation executable I had downloaded from Corel's website, downloaded a second installation executable from Corel's website, and attempted to install from the file I downloaded from Corel's website.  The installation process ran as before, and I attempted to start the application with the same result as before; nothing happened.  Finally, I cleared the Windows Temp Files one last time, and held down the Shift key while starting the application, with the same result as before... the Win10 blue wheel spinning for 3-5 seconds and then closing.

My hardware is an HP Envy laptop with the following specifications, all of which appear to exceed Painter 2020's specifications:

  • 16 GB DDR4-2400 SDRAM (2 x 8 GB)
  • Intel® 802.11b/g/n/ac (2x2) Wi-Fi® and Bluetooth® 4.2 Combo
  • 17.3" diagonal 4K IPS anti-glare WLED-backlit (3840 x 2160)
  • Windows 10 Pro 64
  • DVD-Writer
  • Intel® Core i7-8550U (1.8 GHz, up to 4 GHz, 8 MB cache, 4 cores) + NVIDIA® GeForce® MX150 (4 GB GDDR5 dedicated)
  • 1 TB 7200 rpm SATA; 128 GB M.2 SSD 

My software is Windows 10 Pro 64-bit with Norton 360 antivirus.  Painter 2020 doesn't start regardless of whether antivirus is enabled or disabled, so it's not an antivirus issue.

My Painter X3 continues to work fine, but obviously I'm looking forward to all the new features over the past five years.

Can anyone help me solve this problem?

Thanks!
