RE: PostgreSQL 13.9.3 Uninstall fails with "Unable to initialize any installation mode"

Hi Adrian,
I downloaded "postgresql-13.9-3-windows-x64.exe" from
https://www.enterprisedb.com/downloads/postgres-postgresql-downloads.

I went to Windows 11 Apps > Apps & Features, found PostgreSQL 13 and used the Uninstall option from there. I also tried
executing"C:\Program Files\PostgreSQL\13\uninstall-postgresql.exe" directly with and without Compatibility mode and had
thesame problem.

Where did you get the package you installed from?

What where the steps you took to uninstall?
