PSE 2021 Installation stops dead, no error

Question

Apple MacbookPro, 2015 vintage, MacOS 11.4, 16GB RAM.

Installation dtops dead at 91%; no error message. Activity monitor shows two PSE2021 apps executing, one is marked unresponsive.

I had the Monitor kill the unresponsive module. The other gave "unknown error" message and offered a window "Quit." Clicking on that initiated activity that is going on now for half hour. What gives?

I was hoping to re-statrt one more time before asking for help but now I'm at a loss. The last time I had installation problem like this was on a Windoz

Any help would be appreciated and TIA.

Pete

Thank you for your help.Actually I was able to resolve the problem shortly after asking for help by deleting all new modules; downloaded a new copy of the installer and restarted the installation. Everything went smooth this time and I had Photoshop Elements up and running in twenty minutes or less.Thanks for your help once again.Pete

Pay particular attention to Photoshop's new GPU requirements. See links below.
