File selector and Help button (Modern UI)

[norial]

hello,
how can I open a file selector dialog during the install?
If I found more then one file with the same extension the user must select the right one.

my other question is: how can I insert in all dialogs a button called 'help'. This button shall open a new window/dialog with extra informations or a help file.

1) Use InstallOptions.

2) Showing a new dialog when a button has been clicked is not possible without modifying the source code.
