The ProductCode has implications on what type of upgrading you do. If you change the ProductCode you must use a major upgrade. You'll want to review all of the options in the MSI SDK before making a blanket decision.
No, Component GUIDs are much more subtle than that. Specifically, a Component's contents cannot change (once you distribute them). To be more specific, you can add newer versions of the same file or new values for the same registry key+name but you can't change what is in the Components. I have a long blog entry about that here: http://blogs.msdn.com/robmen/archive/2003/10/18/56497.aspx -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Nick Johnson Sent: Thursday, March 15, 2007 1:25 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Product codes and component guids Is there any reason not to have a script automatically regenerate the product code for each build? To my understanding, it has to change with every release anyway, so why not automatically generate it? Also, it's my understanding that component GUIDs are supposed to change whenever their contents change. What's the best way to handle this? When we're making a release, it's not immediately obvious what components have files that have changed since the last release, and there's no way we can regenerate the guid on a component every time anyone makes a change to any of the files it's composed from. -- View this message in context: http://www.nabble.com/Product-codes-and-component-guids-tf3410752.html#a9502841 Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------- Take Surveys.
