I just run postgresql_17.3_1_windows_x64 installer from their website. Agree on admin window, and then this error pops up. Maybe it is because of Win - 10 user name on my local machine. Anyways this is what I get:
This is what I get on [System.Globalization.CultureInfo]::InstalledUICulture:
LCID Name DisplayName
1033 en-US English (United States)
Looks like a permission issue. try install it via a package manager like Chocolatey.
