Slip in a single file
Is there a way to modify a single file in an installer without building the whole thing?

So to keep the story very short, I just want to take our existing NSIS installer, and replace a single file(a *.mdb file), without rebuilding the installer. I've heard that it is just a 7zip format, but I have a feeling that I would break whatever verification/integrity check NSIS does when my installer runs.

You can't without breaking the integrity of the installer. If you're willing to live with CRCCheck off, it's possible. Simply don't use solid compression, use SetCompress off around the file you need to change and modify it directly in the installer.
