This seems to work ok with simple msi files. However, trying to get Burn to do what I want is a puzzle I need help with: 1. It appears that I will have to use a new UpgradeCode for each Major.Minor version of a bundle since I don't have the equivalent of UpgradeVersion elements for bundles. If I do this I would be tempted to do the same with the msi files that make up the bundle in order to keep things consistent. 2. I can't figure out any way to get a bundle to downgrade a version. It appears that I'll have to flag the downgrade as an error and require the user to uninstall the previous bundle. I guess you could argue that the need to downgrade an install should be rare enough that we don't need to make it convenient. let me know if I've missed anything or there are other approaches. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Bug-UpgradeVersion-element-causing-LGHT0094-error-tp7579387p7579408.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
