Hi all - really glad to see 3.6 is out ! We have an MSI with upgrade-related
logic implemented by the MajorUpgrade element: Specifically, we don't want
upgrades or downgrades to occur automatically (the user is prompted to use
Add/Remove Programs instead). Here is an excerpt from Product.wxs :
<MajorUpgrade Disallow="yes" AllowDowngrades="no"
DisallowUpgradeErrorMessage="An earlier version of [the app]
is installed. [Use ARP]."
DowngradeErrorMessage="A later version of [the app] is
installed. [Use ARP]."/>
With Wix 3.5 we were using the old Visual Studio bootstrapper (the app requires
.NET 4.0). Now that 3.6 is out, I came up with a bootstrapper (standard BA
with custom theme) and noticed it implements auto-upgrade logic (assuming the
upgrade code remains constant): if the version number is bumped up, the old
version gets silently uninstalled. Is there a way to declaratively prevent
this, much like what we are doing in the MSI ? I saw a post on stackoverflow
about this from back in July regarding OnPlanRelatedBundle, but is there a way
to do this without writing a custom BA ?
Thanks for any info !
-Rob
