If you only need a special license for each language, you can specify the LicenceFile parameter in the [Languages] entry.
If you want to show two separate licenses, you will need to add [Code] to do it yourself using the CreateOutputMsgMemoPage() function and loading another license file using somethign like:
ExtractTemporaryFile('additional licence.txt'); LoadStringFromFile(ExpandConstant('{tmp}/additional licence.txt'), LicenceText); LGPLPage.RichEditViewer.RTFText := LicenceText;
If you need a separate set of "Agree / Disagree" buttons, you will also need to create and add them to the page and enable / disable WizardForm.NextButton as necessary.
