[I posted this on microsoft.public.platformsdk.msi last week, but didn't get
any bites. Maybe wix-users will have some advice.]
I'd like to get some advice from the MSI gurus. I'm using WiX, but my
question is really about the best way to [ab]use the MSI engine.
I'm trying to migrate an installer from a script-based system to MSI. I've
got to deal with binaries that I don't control, and that don't follow MSI's
versioning rules. In particular, the EXE/DLL versions don't include a build
number, just a major/minor version, which only increments once per public
release. I get a new set of files every week, and need to produce an MSI
for internal testing. I need this week's MSI to upgrade last week's MSI. I
can't require a manual uninstall of the prior build.
I came up with a solution, but I'm not sure it's the right one. I generate
a new product code on every build (so every build looks like a major
upgrade). I detect when I'm doing a week-to-week upgrade and sequence the
RemoveExistingProducts action for that case, as well as an upgrade from a
prior version. This seems to work, but it generates a warning during
validation in Orca.
<Product Id="????????-????-????-????-????????????"
UpgradeCode="..." Name="..." Manufacturer="..."
Version="1.5.0.0" Language="1033">
<Upgrade Id="...'>
...
<UpgradeVersion Property="SAMEVERSION"
IncludeMinimum="yes" IncludeMaximum="yes"
Minimum="1.5.0.0" Maximum="1.5.0.0" />
<Property Id="SAMEVERSION" Secure="yes" />
</Upgrade>
<InstallExecuteSequence>
...
<RemoveExistingProducts After="InstallValidate">
PREVIOUSVERSION OR SAMEVERSION
</RemoveExistingProducts>
</InstallExecuteSequence>
I also tried setting the REINSTALLMODE property, to force files with the
same version to be reinstalled, but validation complains about this too.
<Property Id='REINSTALLMODE' Value='emus' />
So, what do you think? Am I doing this the best way? Any other
suggestions?
