Thanks for the reply. But we are encounting an error "ActiveX Component cant create object". Is there a possibility that those two versions have the same dll names or using the same component with the same name. That why the system is confused on which to call?

is it possible for Chart fx 5.5 to be overwritten by Chart fx 6.2 installer without conflict. If my application has already adjusted programmatically for Chart fx 6.2. Or is there a way that i dont need to uninstall Chart fx 5.5, and just install 6.2 on top of it?
