Repackaging installer

[japa77]

Is it possible to extract windows installer created with NSIS, change content of one text file and repackage the installer again? We would like to avoid building the complete packages from scratch.

No it isn't. Instead, consider downloading the file instead. If it's only settings that change, consider appending those settings to the end of the built installer and reading them using FileReadByte.
