How to show several licenses in the installer

I use the Inno Setup to create installer for my program. In my program I use third-party libraries, so I have to show license information for each of them. also I want the installer to show certain license files to chosen language. I know how to switch between license fi开发者_如何学Cles if I have 1 license form.

I've looked in google for whole day but didn't find anything

how can I show several licenses?

You can make each license file match the language file by removing the LicenseFile directive from [Setup] and putting it in the [Languages] like this:

Name: "english"; MessagesFile: "compiler:Default.isl"; LicenseFile: "English License.rtf"
Name: "chinesesimp"; MessagesFile: "compiler:Languages\ChineseSimp.isl"; LicenseFile: "Chinese SIM License.rtf"
Name: "chinesetrad"; MessagesFile: "compiler:Languages\ChineseTrad.isl"; LicenseFile: "Chinese TRA License.rtf"
etc...

Hope that helps

You can use the CreateOutputMsgMemoPage to create a page with the memo box on. You can then adjust the sizing and add the agree/disagree boxes.
