InstallAware

I have a setup with English and German translation and copied all files to a new folder for another software, renamed the files.
The setup is working, but the checkbox for Display language selection box has been dissapeared
How can I make the setup to display the language selection checkbox again ?

Thanks !

If you removed some support files from your project (the ones that the Localization Wizard automatically adds for you), this will happen. Please add back in the language files, or run the Localization Wizard again on another project to see which files you need to add back in as support files.

I did not remove any file.
I have re-imported the translation strings and now it works.
