I haven't done this myself so I was just thinking out loud to try to give you ideas and an alternative perspective.
If it's a hotfix only bundle, then to me it feels like a different payload. Also looking at the documentation and seeing the RelatedBundle/@Action='Patch' to me seems like that is how patch only bundles were intended. Main Bundle: v1 -> v1.1 -> v1.2 Hotfix Bundle |-> v1.1 -|-> v1.2 Assuming the ASCII art comes through above, I would expect Main Bundle v1.1 to have a different upgrade code to Hotfix Bundle v1.1. For me, I've avoided hotfix bundles but instead I have a single Bundle where I don't embed any of the installers, and I simply slipstream the MSP's after I hit RTM (the update v1.1 is the same bundle as the install v1.1). -----Original Message----- From: tom [mailto:tomer.d...@intergraph.com] Sent: Sunday, November 17, 2013 12:19 PM To: wix-users@lists.sourceforge.net Subject: Re: [WiX-users] Why do i need to add RelatedBundle in the 'main' bundle? Thanks Yes purely hotfix...only msp Ok... sharing same upgrade code in both HF and different upgrade code in RTM..... this we didnot try yet :) Also you say "it back to RTM. To me it makes the most sense to have HF1 and HF2 both share a unique upgrade code that is different than the RTM upgrade " Why is that? as far as i know the upgrade code in msp must be the same as the product it patch(i understand it is not releated to bundle upgrade code) Thanks very much for your help. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Why-do-i-need-to-add-RelatedBundle-in-the-main-bundle-tp7590702p7590704.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ DreamFactory - Open Source REST & JSON Services for HTML5 & Native Apps OAuth, Users, Roles, SQL, NoSQL, BLOB Storage and External API Access Free app hosting.
