Assuming that PIDKEY is just a property you're setting, you'll
probably want to set the property to a default value (e.g. DEMO) and
do a RegistrySearch to overwrite it if you can find an existing PIDKEY
in the registry.
<Property Id="PIDKEY" Admin="yes" Secure="yes" Value="DEMO">
<RegistrySearch Id="RegSearch_PIDKEY" Root="HKLM"
Key="SOFTWARE\My Company\My App\1.0" Name="SerialNumber" Type="raw" />
</Property>
