Hrm, something like that might worked. Just to make sure I understand
what's going on, it sounds like there isn't a way to do this with out
changing the version number? I'd love to just keep my installer version
at 1.0.0 and allow it to overwrite all other 1.0.0 installations, even
though I'm making changes to the binary it's installing. Yeah, this
might lead to a case where an old binary is installed over a newer one,
but that's not really a problem for us.
Also, is the installer's version number supposed to have some connection
to the version of the application that's being installed? Feels a
little strange to keep bumping up the version number if the underlying
binary isn't really changing much.

I did something kind of like this for a very lightweight install: I
made every package into a major install, using the ??????? syntax to
update the appropriate UIDs and using a upgradecode, and generated a
new version number each time using the year, month, day, and time of
day as the major/minor/rev number, something like 2008.0502.1645 which
is always a newer version than the one installed - it seems to just
install fine over the last one every time. Details a little hazy as
it's been a while, but sounds like it could work for you.

Hey guys,
I'm building an application that's going through lots of small
revisions
right now. It's annoying to install, though, because we must first
uninstall the previous installation, then install the new one. I'm
trying to figure out how to fix this. The application is internal,
alpha quality stuff, so I don't want to maintain version numbers and
stuff, I think I just want an installer that can install over itself.
Is it possible to do this? I don't want to change GUIDs or version
numbers with every build, I'd just like to have an installer that
copies
over the existing files and registry keys. My installation process is
pretty simple (just copying a couple files and setting a few registry
settings). I've been reading through this page, but it seems like
more
than what I want or need: http://www.tramontana.co.hu/wix/lesson4.php
I naively tried adding an UpgradeCode to my product then adding an
Upgrade element that references that GUID, but I'm not sure what to do
with it. If I run the exact same installer twice in a row it installs
both times, but if I build a new installer I get the "this product is
already installed" error message. Any suggestions?
Thanks!
Colin
