Hello,
I was trying to get something to show before the "welcome dialog" but this is better than nothing.
If you have any prerequisites in your package and don't mind using an .EXE package, you could also look into the
"Display Information dialog" from Bootstrapper UI functionality. When setting
prerequisites as pre-install, the bootstrapper dialogs will be shown before the main installer dialogs.
here does not seem to be any way to make the readme.rtf language dependent
If you're looking to show the readme text depending on the target machine language, you can follow
"How do I localize the EULA and ReadMe text?" article for guidance.
All the best,
Mihai
