I am positive because of the associated updater log, among other reasons,
which shows version 1.0.39-20180121191330+5e57981 (that's the semantic
version, the windows version being applied 2018/01/23 11:57:11,
then the updater considers that version current when it checks for the next
2018/02/16 19:30:03 INFO Checking for update, current version is
(updater gets this version by running the installed program with the
"version" argument.)

Again, our custom actions are supposed to close our processes in the
upgrade case, but if upgrade case is not detected, they can't close the

I guess we could hack around this with some registry entries, but detecting
+ applying upgrades is one of the main reasons to use a tool like Wix I
thought. Again, this happens only intermittently, and didn't seem to happen
ever with Wix 3.9.

Thanks again, everyone, for taking a look.
