How can I build a patch?

[Thisalike]

I want to change some little things in a published version of a game. How can do that? Can I create a patch somehow? I don`t want to force the people to download and reinstall a complete new version.

I'm sure many other and free patch makers exist:

Or you can make an installer using the free Inno setup tool only to include the files you want to overwrite...

Good luck,
