Hi, I've unfortunately made a bad decision a few months ago which is the cause of this query. We have an installer which we've released 3 versions of in the past. All cosmetic changes to UI etc, components were unchanged between all 3 versions. V1.0 & v1.1 have product code A. I (stupidly) released v1.2 with product code B. This works as a major upgrade to v1.0 or v1.1 quite happily however since it's cosmetic changes to a 400 MB MSI the majority of our users won't have bothered with updating since the actual content is no different. Don't ask why I changed the Product code as I really couldn't tell you what I was thinking then & I really wish I hadn't now.
I now need to create v1.3 which has a new component with 2 new files in it. I have created an MSP which targets v1.2 as a minor update as I haven't changed the product code between v1.2 & v1.3. I would ideally like to create an MSP which targets all 3 earlier releases but this doesn't seem possible. I'd be happy to create 2 (or even 3) separate MSP's & bootstrap them together so the correct one runs on the users system. The problem appears to be that creating Major Upgrade patches is as far as I've found, impossible. MSDN says they're possible (http://msdn.microsoft.com/en-us/library/aa370579.aspx & http://msdn.microsoft.com/en-us/library/aa367571.aspx). However the WiX documentation says they cause problems & aren't supported -> http://wix.sourceforge.net/manual-wix3/patch_restrictions.htm which is backed up by Heath Stewart's blog post -> http://blogs.msdn.com/heaths/archive/2005/08/22/454552.aspx Has anyone created & deployed a Major Upgrade patch since the advent of Windows Installer 3.0? If it helps I'm using the msimsp/patchwiz method of creating patches but am not averse to going the WiX/pyro route if needs be. The v1.2 -> v1.3 MSP I've created is 185 kB which updates a 410 MB MSI so you can see why I would like to create MSP's rather than forcing users to download & upgrade using the full MSI.
