Major upgrades have a property that gets set when the older version is
found. To use Bob's example:
<!- Major upgrade ->
<Upgrade Id="$(var.UpgradeCode)">
<UpgradeVersion Minimum="$(var.ProductVersion)" OnlyDetect="yes"
Property="NEWERVERSIONDETECTED" />
<UpgradeVersion Minimum="1.0.0" IncludeMinimum="yes"
Maximum="$(var.ProductVersion)" IncludeMaximum="no"
Property="OLDERVERSIONBEINGUPGRADED" />
</Upgrade>
OLDERVERSIONBEINGUPGRADED can be used as your condition.
If you're referring to an installed product that is being uninstalled and
upgrades, use UPGRADINGPRODUCTCODE as the condition.

Subject: [WiX-users] Condition for Upgrading...
Hi folks,
I am confused, I looked within the WIX userlist and Googled this but I seem
to have mixed results...
I want to run a custom action on an Upgrade only.. I currently have it as:
<Custom Action="CA_CheckIfServerOnLine" After="InstallInitialize">NOT
Installed AND SERVER_INSTALL="0"</Custom>
But in some cases it is being run on a fresh install :(
I am using the MajorUpgrade element for upgrades...
Thanks,
Steve
