site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com Thanks Stephane. What is a diff? Andrew What about a payload that is a diff? PackageMaker supports this. The inconvenient is that it probably only works to update a specific version (contrary to what you could/can do with InstallerVISE) Hi, The only way I can think of doing it is to create hundreds of different choices. Which I can do with some time, but then hundreds of receipts get put on the user's system which seems a little "unprofessional" Does anyone know a better way? I would be very grateful for any tips... _______________________________________________ Do not post admin requests to the list. They will be ignored.

I know that I can set a requirement for a choice (only install if a particular file exists on target), however I need to do this for hundreds of files.
