User story

As a setup developer, I want give user to select option if feature is installed or not (separate MSI under bootstrapper application).
I have variable

<Variable Name="FeatureInstall" Persisted="yes" bal:Overridable="yes" Type="numeric" Value="1" />

then on upgrade I want check if previously feature was installed

<util:ProductSearch Id="Feature_Installed" UpgradeCode="0-1-2-3-4"
  Result="exists" Variable="FeatureInstall" After="UpgradeCheck" Condition="IsUpgrade = 1" />

and on option page user is able to toggle feature on or off

<Checkbox Name="FeatureInstall" X="30" Y="124" Width="-11" Height="17" TabStop="yes" FontId="3">Install feature</Checkbox>

Current situation:
There is ProductSearch Result="state" and if msi was not installed, then result value will be 2 (ABSENT) and it will trigger the checkbox on.

Proposal

Add exists option to ProductSearch Result
