I added the following property assignment using ComponentSearch and 
prerequisite check and the property assignement isn't happening in case where 
prerequisite msi is known to be installed and known to have product id guid 
value specified in componentSearch.   Am I misinterpreting the use of 
ComponentSearch to detect whether or not someother msi owned product is 
installed on a target host?

<Property Id="MYPREREQUISITEMSITHATMUSTBEINSTALLED" Secure="yes">
    <ComponentSearch Id="MyPrerequesiteMsiThatMustBeInstalledSearch" 
Guid="<product id guid value of my prerequisite msi that must be installed " />
</Property>

<Condition Message="[ProductName] requires <my prerequisite msi that must be 
installed name> to be installed.">
    Installed Or MYPREREQUISITEMSITHATMUSTBEINSTALLED
</Condition>

is there a canned way for authoring a prerequisite that checks for the presence 
of another msi installed product, e.g. w/o using registry or directory or file 
searches?
