I thought it treated files like MSIs and only compared the first three
digits, so I glanced over the version number. Comparing them again, OLD >
NEW.

MSI (s) (88:A0) [20:12:50:115]: Disallowing installation of component:
{8B97BC16-7D4D-45CD-A3E3-903C60868202} since the same component with
higher versioned keyfile exists
Now that log entry finally makes sense...
*head->table*
Thank you!
So I guess the question becomes how to best downgrade a file during a
major upgrade...
We have no shared components or merge modules, so we always want to put
exactly the version in the msi on disk, even if that means downgrading.
At least according to this (
http://stackoverflow.com/questions/4227456/windows-installer-deletes-versioned-file-during-product-upgrade-instead-of-down?rq=1
) post, scheduling before Costing should work, so I will try that.
Thank you again,
Lukas

installed
Windows Installer only ignores the 4th digit of the MSI version. It'll
evaluate all four places of a file version.

Subject: Re: [WiX-users] Major upgrade: a few files are not installed
I opened up both MSIs in Orca and compared their version numbers.
The missing files are different, but their version only differs in the
forth place (which is ignored by MSI). The fourth place of the upgrading
files is actually higher, so there are no higher version components on
disk.
Files which are exactly the same (same hash and of course same version
number) do exist on disk after the upgrade.
Files whose version differs in the first three places are also correctly
replaced.
The affected DLLs are kind of like third party - they are built
internally, but the version number is defined by the incremental build and
I have no way to change the versioning algorithm (different team, ...).
I have also googled some more, and one option seems to be to schedule
RemoveExistingProducts even earlier, before costing. Would there be any
downside to that?
Sorry to take so long to follow up and thank you, Lukas
