I have a ServiceInstall component in a WiX installer where I have a requirement to either start auto or demand depending on parameters passed into the MSI.

So the Xml element in question is

<ServiceInstall Vital="yes"
     Name="My Windows Service"
     Type="ownProcess"
     Account="[SERVICEUSERDOMAIN]\[SERVICEUSERNAME]"
     DisplayName="My Service"
     Password="[SERVICEUSERPASSWORD]"
     Start="demand"
     Interactive="no"
     Description="Something interesting here"
     Id="Service"
     ErrorControl="ignore"></ServiceInstall>

WiX will not allow using a PArameter for the Start attribute, so Im stuck with completely suplicating the component with a condition, eg/

<Component Id="ServiceDemand"
                 Guid="{E204A71D-B0EB-4af0-96DB-9823605050C7}" >
        <Condition>SERVICESTART="demand"</Condition>    
...

and completely duplicating the whole component, with a different setting for Start and a different Condition.

Anyone know of a more elegant solution? One where I don;t have to maintain 2 COmponents whjich do exactly the same thing except the Attribute for Start?
