In order to make your application use FlowChartPro dll without registration from local directory(side by side), you have to
add the following into manifest file:

...........
<file name="flowchartx32.dll">
<typelib tlbid="{69ECBBD3-5C2A-4a84-ABEC-23937DBF1B54}" version="1.4"
helpdir="" />
<comClass clsid="{F025BF4E-4081-4C02-86E6-6602AEE846F6}"
threadingModel="Apartment" progid="MindFusion.FlowChartPro"
tlbid="{69ECBBD3-5C2A-4a84-ABEC-23937DBF1B54}" />
<comClass clsid="{CECBEE14-3E53-444e-9C79-913D4564EC16}"
threadingModel="Apartment" progid="FlowChartPro.LayeredLayout"
tlbid="{69ECBBD3-5C2A-4a84-ABEC-23937DBF1B54}" />
</file>
..................

It would load the local dll,even if you register another flowchartx32.dll in another
location!

The only drawback, is you have to add each ComClass id you would use.I used
only Layered Layout.
You can find another CLSIDs from flowchart.h
