I have no i18n folder under app so I can not install any language packs? Any ideas? I have installed using softaculus on a2 hosting. Is there anything I am not understanding?
You should install language packs using composer. In that case, modules (becasue lanaguge packs are modules too) will be placed into /vendor directory.
Another option is to create you own package or install an existing one into: /app/i18n/
I'll recommend you to read http://devdocs.magento.com/guides/v2.1/frontend-dev-guide/translations/xlate.html
In Magento2 there are 2 ways to install Component(Module, Theme, Language Pack).
1 . Through Composer
2 . Manually Installation.
Step 1: Download/purchase the extension
Step 2: Unzip the file in a temporary directory
Step 3: Upload it to your Magento installation root directory
Step 4: Disable the cache under System >> Cache Management
Step 5: Enter the following at the command line:
php f bin/magento setup:upgrade
