Failed to initialize 13.2-1 cluster on Windows

Hello,

I'm trying to install 13.2-1 on Windows 10. Previous version was 10.5,
installed using the EnterpriseDB installer, without any problems. That
version was completely removed before attempting to install 13.2.

EnterpriseDB installer failed to initialize the cluster. The error says
that initdb can find postgres executable but it's of a different
version. I've read some threads that described permission problems, but
I couldn't solve it. What I've tried:

- Installing everything by default (including all default folders)

- Installing on different folders, on C: and D: disks, outside of
Program Files.

- Installer is run with "Run as administrator" option

- Tried to execute "initdb -D path/to/data/folder" manually after the
installer failed. Same message

- Manually altered permission on installation folder, giving local users
full control on the whole folder (programs and data)

- Tried the zip file without installer. Uncompressed everything on a
folder outside program files and running initdb by hand. Error: "initdb:
error: El programa «postgres» fue encontrado por
«C:\Apps\PostgreSQL\13\bin/initdb», pero no es de la misma versión que
initdb." BTW, I don't know why messages are in spanish. Although I'm
located in Argentina, my windows and every program is installed in
english, and english is selected as primary language. But, nevertheless,
that's unimportant. Translation is "postgres program was found by
initdb, but it's a different version".

- When executing postgres.exe directly, it says "FATAL: XX000: postgres:
no se pudo localizar el ejecutable postgres correspondiente. UBICACIÓN:
getInstallationPaths,
d:\pginstaller_13.auto\postgres.windows-x64\src\backend\postmaster\postmaster.c:1489".
That would translate as "could not locate corresponding postgres
executable".

I've read somewhere a recommendation to create a separate user
"postgres". Although that's common practice on Linux, I've never done it
on previous Windows installations. Would that be something to try?

I'm running out of ideas for what else to try. Any help will be much
appreciated.

Regards,

Martin
