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.
