The location of the Publisher configuration file called ‘iap.ini’ is

C:\ProgramData\EsriUK\InstantAtlas

You can open this file with a text editor such as Notepad.

Changing the Interface Language of the IA Tools

You can add a new setting to control the language for the interfaces of the InstantAtlas tools (Publisher, Designer and Style Editor). The default for this is UK English. To make the software use a language pack, you must add one of the settings shown in the table below on a new line below [gui]:

Setting	Language you wish to run the software in…
locale=en_US	US English
locale=de	German
locale=es	Spanish
locale=fr	French

If you would like the interfaces to display in Spanish for example, your iap.ini file should look like that shown below.

Save the iap.ini file and start the Publisher. Assuming you have installed the correct language pack, the interface text will now be in the language that matches your locale setting.
