Check out the File Versioning topic in the MSI SDK. That is what will control how your files get upgraded. Changing the GUID on the Merge Module won't affect them. The Merge Module signature has a version, I would suggest leaving the GUID the same and just up'ing the version number... unless the Merge Module is some breaking change and installs everything to completely different locations.

Now I've got to recompile my wix files to pick up the newest versions of the executables (bug fixes, new features etc). Should the GUID in <Module> be changed to indicate the file contents have changed, or do I keep the same number and rely on whoever writes the installer to change the Upgrade Code? I need Windows Installer to recognise that these are replacement files, not new files that just happen to install over the top of existing files.
