Unlikely as it seems, if there is a WiX bug then open your MSI file with Orca and look at the InstallExecuteSequence and see where RemoveExistingProducts is sequenced relative to InstallValidate or InstallInitialize.
As John says, you may not have correctly specified enough to make it an actual major upgrade. Common issues tend to be failure to increment ProductVersion in the first three fields, and per user will not upgrade per machine (and vice versa). That's what verbose logs are for :) --------------- Phil Wilson On Tue, Nov 4, 2014 at 6:26 AM, John Cooper <jocoo...@jackhenry.com> wrote: > I've been using Burn since it came out in Wix 3.6 with 20 product installers. > MajorUpgrade has been an important requirement for all of them.
