Subject: [wix-users] MSI patching question

Does anyone here create .msp patches?

Our build system re-builds and re-signs every file before packaging into the MSI. Because of this, when I take two MSIs (from two different builds) and attempt to make a patch between them, every file is included! How do people work around this??
