Multilingual project, does not work after installation

[sn_race]

Hello,
I developed this sample test to create a Setup project for a Multilingual WinForm application.

I used Visual Studio 2022 and .resx files to translate into three languages.

The test project has only Form1 as a user interface, so the .resx files are:

Form1.resx = Italian (default)
Form1.en.resx = English
Form1.ro.resx = Romanian

I managed the language change with:

CultureInfo ("it");
CultureInfo ("en");
CultureInfo ("ro");

And I update the components with:

this.Controls.Clear ();
InitializeComponent ();

When I start the project from Visual Studio everything works ok.
I create the Setup and only the Italian language works (default), when you change the language you see the components refresh, then the update but it does not load the selected language.

I think the default resx incorporates it into the setup project and the others don't, it's just a theory.

What could I try to solve?

Here 2 pictures to better understand:

Don't clear the controls. Reapply the new resources. See this StackOverflow response:

Changing CurrentUICulture at runtime in a Localizable Form in WinForms

I have been searching about how to change the language of a Form that has the Localizable attribute set to true. https://msdn.microsoft.com/en-us/library/system.threading.thread.currentuiculture(v...

Ok, many thanks,
i did as it says on StackOverflow,
if I run from Visual Studio it loads me the text of the Button and the Label but it doesn't load me all the rest, so the Text of Form1, the contents of the ComboBox and the languages for the MessageBox, after the installation on win it continues not to load anything , only the default language

You mentioned that the problem also only occurs after installation. What did you use to install your app? Did it also install all the satellite assemblies?

Anyway, have you looked at this guy's alternative approach to changing cultures on the fly?
