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,
