Hi, In the new Installer, I've externalized the strings to .properties files. I copied what was in RuntimeLocale.as to flex-utilities/installer/src/properties. Please review for your native language.
Then in flex-sdk/installer.properties there are other .properties files that are used by installer.xml, especially when installing using Ant. There are some strings in each locale that needs translation. Also, in flex-sdk/apache-flex-sdk-installer-config.xml are other strings that need review. Thanks, -Alex
