Elements 19 application install damaged

[#1]

"Your application install seems to be damaged, Please reinstall the application." during Elements 19 re-install after formatting. This has happened after 6 tries. Any ideas?

Thanks. Did that...same result. Adobe insisted that a new copy (2020) had to be purchased to be compatible with Catalina. THANKS ADOBE! Just purchased '19 in July...
