What's happening when REP is just after InstallValidate ("early in the
install") is that the older product is uninstalled and then the new one is
installed. In this situation Tom's data file just gets removed and then
installed by the new product.
When REP is "late" in the install the new product is installed on top of the
older version, during which the file overwrite rules are used and component ref
counts are incremented (so your guids should be consistent for files you care
about, and Chris's side effects). Then the "uninstall" happens, which mainly
consists of decrementing the component ref counts.
So I think we're both saying the same thing, and I don't think my earlier
statement that "A major upgrade will not use file update rules if it's
sequenced early in the install, such as just after InstallInitialize"
contradicts anything you're saying.

Phil are you sure about this.. (not trying to be difficult I would be
interested to understand what your getting at here.)
My understanding of the sequencing relating to upgrades is the opposite of
what you suggest.
by moving the RemoveExistingProducts action earlier in the sequences you are
effectively removing the older product prior to installing the new one.
By leaving the RemoveExistingProducts later in the sequences you will have
the opportunity to leave components on the machine during installation of
the newer version. See this post for more details as its quite complex to
explain. This would require that you match component ID on the items you did
not wish to upgrade.
