Have you considered using NSIS for creating Windows installers?
For my church needs I've created own installer using unicode NSIS branch ( http://www.scratchpaper.com/ ).
Because of size I uploaded it to my page. You can get it from my site:
http://files.zibricky.org/opensong_inst_script.7z
Archive is in 7zip format ( http://www.7-zip.org/ )
Unicode branch solves some localization issues with original NSIS.
I'm pretty sure that these issues are also present in INNO installer.
The only disadvantage I see is that unicode NSIS breaks support
for win9x.
Do you plan to still support win9x users? Are there many win9x user?
I created this installation script with localization in mind. For example
I added the possibility to use localized license info.
I should be able to adapt this script to general OpenSong needs.
I could also add the possibility to choose language and data folder
during installation.
Just let me know.
