When supporting downgrades, set the REINSTALLMODE property. Specifically, out of the following set of letters, you want either d or a: a, c, d, e, o, p. Thus, a good value to use would be "amus".

I find that if RemoveExistingProducts comes after costing, then the current files get removed and the new files don't get delivered. Removing the existing product removes the existing files, which affects the actions the installer needs to take. Before, the files were not supposed to be installed because there were newer versions on the system. After the product has been removed the files are no longer there and the ones in the downgrading MSI need to be delivered, but aren't. Is there a way around this? The files being downgraded are not shared by other products. Rob On 12/07/2010 14:06, Bob Arnson wrote: > On 7/12/2010 8:17 AM, Rob Hamflett wrote: >> Some more info.
