If this is an upgrade to the same product, then the UpgradeCode should
be the same and it should remove the existing product if you have a
proper Upgrade table setup. (No need for a custom action.)
<Upgrade Id="$(var.UpgradeCode)">
<UpgradeVersion Minimum="$(var.ProductVersion)"
IncludeMinimum="no" OnlyDetect="yes" Property="NEWERVERSION_INSTALLED"
/>
<UpgradeVersion Minimum="$(var.MinimumUpgradeVersion)"
IncludeMinimum="yes"
Maximum="$(var.ProductVersion)"
IncludeMaximum="no"
Property="OLDERVERSION_BEINGUPGRADED"
MigrateFeatures="yes" />
<UpgradeVersion Property="ANYVERSION" IncludeMinimum="yes"
Minimum="0.0.0.0" Maximum="99.99.99.99" IncludeMaximum="yes"
OnlyDetect="yes" />
</Upgrade>
The next question is when do you have RemoveExistingProducts scheduled?
<InstallExecuteSequence>
<RemoveExistingProducts Before="InstallInitialize" />
</InstallExecuteSequence>
(You can schedule it before InstallInitialize which will remove it
before installing the new product, or you can schedule it after
InstallFinalize. If you do it after InstallFinalize, then components
which aren't changed between packages won't change.)
What component is it that is refusing to update? Is it a binary file
with version info? If so, the version number needs to be different
(possibly higher) or the upgrade won't update it. If it's a text/data
file, then if it was modified post install I also believe the
uninstaller won't remove it.
If it is a user modified data file and it must be removed, then you can
add
<RemoveFile Id="Purge.UserModifiedFile" Name="FileName.ext"
On="uninstall" />
to the component. (Note, this won't fix existing installers in the
wild, but will fix future updates to a new installer released.)

Subject: [WiX-users] msi made up of only 1 custom action
Hello,
I am only 2 weeks into learning WIX and haven't done much beyond the
installer stuff that comes canned in VS so bear with me. I was
confronted
with a challenge at work concerning an upgrade package that is simply
refusing to replace a file. The guy who normally builds it insists he
has
taken all the usual steps and due to time constraints I have to take him
for
his word.
I was able to write a wix component that uninstalls our products with a
call
to msiexec in a custom action. This project has no file or directory
components, not even a feature (now that I write this I am wondering if
the
lack of a feature is what my problem is). It's a simple dll that makes a
call to msiGetEnumeratedProducts and iterates through each product code
related to a given upgrade code and uninstalls it. When I run this by
itself, it removes the products and all is well.
However, we also want to install the new product so I generated a
bootstrap
manifest, built that and got my msi, the installer and a new setup.exe
which
I imagine wraps the chain that calls each package. When I run the
setup.exe
however, it sees the project with custom actions then acts like its
running
it and proceeds to the exe but it doesn't actually run. Again when I
click
on the msi that is just the custom action that the bootstrap manifest
generated for its output, it runs fine.
I've lurked and know you guys will ask for log files however when I try
and
run the bootstrappers setup.exe (the chain wrapper) through msiexec I
get an
error saying it's not a recognized something or other and won't run and
since that is where the problem exists, im at a loss.
Any help would be greatly appreciated
Steve
