Click Once application doesn't start on a new Windows User

I have a Click Once application installed on a PC with an admin user. I created another admin user and installed the same app, only to find out that is was crashing: App has stopped working. Problem event name: CLR20r3, System argument exception

The reason:

• my app uses a DataSet that has a specific locale, let's say X
• when I created the new user, the setting in Region and Language - Formats - Format wasn't set to X

Resolution:

• I've changed the Format to X and it works fine
