[wix-users] How to downgrade a file to an older version in a patch?

[Carlos Sosa]

I had a similar problem, I ended using a script to remove and another to
copy the new file.
Used a bundle to handle the order.

As you are finding, it is very hard to go backwards in time. Early major
upgrade may be only real approximation of going back in time.

Hello all,

We've ran into a problem with a third-party dll that requires us to
downgrade to an older version (i.e. 5.0 to 4.0).  The patch that upgrades it
is already released, so we can't just undo the change.  So this patch needs
to remove the newer version and put in the older version in its place.

I searched the WiX discussion and internet for methods of doing this.  I
tried different ideas, but they all didn't work.  Here's what I tried:

Remove the component containing the dll, and add the dll as a companion file
in another component.  This resulted in files not actually getting updated.

Replace the component's "File" element with "RemoveFile" and adding a new
component that adds the file back.  This merely resulted in the file getting
deleted, but not restored.

Changed component's "transitive" value from "no" to "yes".  Didn't do
anything.

These are the constraints we have to work around: We cannot open up the dll
and alter its version number.  We cannot rename the dll.  Is there a valid
method?  Or do we need to release two patches, one to remove the file, and
one to add it back?
