So, I’ve been trying to change my Informatica Powercenter display language from Portuguese to English, however I never could find a decent way of doing this trough reg or properties file editing, so I end up doing the normal way, which is, changing your Windows’ Region format .
Here’s a print screen using my computer, Windows 11. See that FORMAT is now ENGLISH (previously it was Portuguese).

Here’s the result, Powercenter display language is now English!

If you guys know how to change the display language in any other way, let me know.
