Subject: [WiX-users] Launch condition on patch not working
My situation is I want a launch condition to fire off if the product has yet
to be installed (it's a regsearch to look for any other related products).
If the product gets installed, I want to make it so the launch condition
doesn't fire off on patch/majorupgrade/etc, basically only evaluate for a
fresh install.
Here's how I'm setting it up (but its failing on any patches).
<Condition
Message="!(loc.IMLaunchConditionOTHERAPPS)"><![CDATA[EXISTINGAPPS=""]]></Condition>
<Property Id='EXISTINGAPPS' Secure='yes'>
<RegistrySearch Id='Registry' Type='raw'
Root='HKLM' Key='Software\CompanyName='Value' />
</Property>
// Clears the prop
<CustomAction Id="SetUninstallLaunchCondition" Property="EXISTINGAPPS"
Value="" />
// Should clears the prop on any scenario other than fresh install
<Custom Action="SetUninstallLaunchCondition"
Before="LaunchConditions">REMOVE="ALL" OR REINSTALL="ALL" OR PATCH OR
MSIPATCHREMOVE OR UPGRADINGPRODUCTCODE</Custom>
Any thoughts? Seems like the CA isn't firing on the patch to change the
prop
