Custom Action execution by feature

I wrote a custom action to create a sc开发者_运维知识库heduled task after install. I do not want the Custom Action to run when the user does not want to create the schedule task. During installation even if I select " Feature will be unAvailable" the schtask is getting created. How do i prevent the Custom Action from executing?

You can set a condition for your CA execution:

<InstallExecuteSequence>
    <Custom Action="ScheduleTaskCA" After="InstallFinalize">
        <![CDATA[&feature_name=3]]>
    </Custom>
</InstallExecuteSequence>

Hope it helps.

Add to your Install execute sequence.

Actually I found out the problem. The &FeatureName = 3 tells me that the feature is to be installed, and the opposite to that, is !FeatureName = 3, which means the feature is installed already. This fixed my problem so the final solution became

&FeatureName = 3 OR (!FeatureName  = 3 AND NOT (Uninstalling OR MSIPATCHREMOVE OR RemovingForUpgrade)

"MyService" is feature Name

"FEATURE_MyService" is my condition Name: I am using checkbox to set the value of FEATURE_MyService property

<Control Id="Chk1" Type="CheckBox" Height="12" Width="110" X="50" Y="199" Text="Portal Windows Service" Property="FEATURE_MyService" CheckBoxValue="0" Hidden="yes">

<Custom Action='CAction1' After="InstallExecute">
    NOT Installed AND <![CDATA[(&MyService=3)]]>

<Custom Action='CAction2' Before='InstallExecute'>
    <![CDATA[(&MyService=3 AND NOT Installed)]]>

<Custom Action='CAction3' After='InstallFinalize'>
    <![CDATA[FEATURE_MyService AND NOT Installed ]]>
