I'm not sure if this is according to Best Practices or not, but you could also change the component code of the file whose version is downgraded so that it is a different component than the "newer" version.

Subject: Re: [WiX-users] Supporting downgrades with Key paths The decision to replace files (or not) is associated with Costing, and that's happened by the time your RemoveExistingProducts runs. You could try sequencing RemoveExistingProducts before CostInitialize. That should behave like a complete uninstall followed by a new install. I've used that, I think I had a support incident with MS on that when there was a problem similar to yours, and it's ok (even though undocumented). But: you probably won't get your features migrated. The lack of integration with the incoming install also means you may see two sets of FilesInUse dialogs, potentially one as the old product uninstalls and another from the new install.

Subject: [WiX-users] Supporting downgrades with Key paths I have a problem with downgrades. I have RemoveExistingProducts scheduled before InstallInitialize. I have a component with the keypath set to a file (.exe) When I downgrade the version number of the exe is older so the install marks the component as not valid for install because a latter version has been detected even thou the RemoveExistingProducts is removeing the entire package. Any ideas how to fix this please? ---------------------------------------------------------------------------- -- Xperia(TM) PLAY It's a major breakthrough.
