We are seeing patch applicability logic not working correctly and leading to incorrect patch sequence getting applied. I looked at the following threadshttps://blogs.msdn.microsoft.com/heaths/2009/04/13/patch-applicability/
and Patch not installing on a particular previous patch
Patch not installing on a particular previous patch
We are using PureWix and have following PatchFamily entry in patch<Fragment> <PatchFamily Id="AgentUpdate" Version="$(var.ProductVersion)" Supersede="yes"/> </Fragment>
var.ProductVersion is actually a file version and is incremented on daily basis.
What I observe is that I can apply my older patch (1.4.0 version) over my newer patch (1.6.2). What am I missing? What check could prevent version downgrade from happening?
Appreciate quick help or pointer with wix detail to handle this downgrading issue.
