Sorry that I didn't make it clear this is already the case (even
though we've been trying to figure out how to avoid doing so, in order
to simplify the upgrade process). But because the uninstaller (of my
app) doesn't uninstall TortoiseOverlays (per TortoiseOverlays'
documentation), so I was not sure if the re-installation (of
TortoiseOverlays) would complicate things somehow.

I presume you meant the old version of my application?

OK.
