The Product Version is tricky with the Windows Installer. MSI only respects
the first three numbers in the version. So, "0.9.2006.1211" and
"0.9.2006.1212" look the same. It's documented in the MSI SDK if you look up
ProductVersion. In general your version should be,
MajorNumber.MinorNumber.BuildNumber.Revision (where BuildNumber always changes
and Revision changes usually when you do an extra build of the same thing...
i.e. it's fuzzy when Revision changes). <smile/>

Subject: [WiX-devs] smooth version upgrade
Hi Justin, guys,
Could you please help me?
I need to develop the installer which will smoothly update my program to the
next version.
I mean that user shouldn't remove manually previous version of the program
before installing new version.
I have used the WiX installer as a sample and after some playing with versions
I decided that it works ok but now I have changed the version and installer
told me that later version is already installed.
I use following format for versioning: MajorNumber.MinorNumber.Year.MonthDay.
I changed old version 0.9.2006.1211 to new one 0.9.2006.1212 and my installer
told that later version is already installed.
How can I fix the problem?
-- My code:
<?define Version = "0.9.2006.1212" ?>
<?define UpgradeCode = "13263952-62A0-49CC-AD60-D8D388C94245" ?>
...
<Condition Message="A later version of [ProductName] is already installed.">
NOT NEWERVERSIONDETECTED </Condition>
...
<Upgrade Id="$(var.UpgradeCode)">
<UpgradeVersion
Minimum="$(var.Version)"
OnlyDetect="yes"
Property="NEWERVERSIONDETECTED" />
<UpgradeVersion
Minimum="0.0.0.0"
IncludeMinimum="yes"
Maximum="$(var.Version)"
IncludeMaximum="no"
Property="OLDERVERSIONBEINGUPGRADED" />
</Upgrade>
--------
Thank you!
Best wishes,
Dmitry Pavlov,
