Generating Patch Files for MSI Setup Files

Building an installer for just about anything with dotNET produces a multi-megabyte setup file which contains mostly dead-weight in terms of original content.

I found myself wanting to avoid transferring these large files each time I made a small update to a program on a remote PC, so I went looking for a compact and simple patch generating tool.

I ended up finding bsdiff.exe and bspatch.exe which require bzip2.exe. Lean, mean, and exactly what I wanted.
