The PortableApps.com Installer (used for individual .paf.exe installers) and the PortableApps.com Platform installer share the same strings for translation. These are a little different than the .locale files included with the platform as they can't be translated and then tested directly by translators. Nor can they use the iniTranslator Portable utility to handle translations.
A zip file with the current strings for English and all other languages can be downloaded here: languages-2024-05-08.zip. These are the same translations included with the current PA.c Installer 3.8.7. You can also see these strings in action with the current PortableApps.com Platform's installer.
You can use the current Google Chrome Portable release to test out other strings including downloading. This way you can see the strings used by the PA.c app installer that aren't used by the platform installer like downloading messages.
Look at the English.nsh as your guide and copy in the missing section to the language you are updating. Switch the ${LANG_ENGLISH} string on each line to the one for your language.
Please post the updated strings as a comment here within PRE tags or on pastebin.com and link to the post.
Thank you all for your help!
BONUS POINTS: When you're done, please consider helping out with the platform localization if your locale isn't yet up to date or needs some tweaking.
