Set the dll destination folder to Windows\System32, and mark it as COM self-registering dll in your installer project.

You might also have to include the MSXML4 runtime and the GdiPlus redistributable package in the installer if you use the Xml Reader/Writer classes or the GDI+ graphics engine.

If your application creates FlowChartX instances dynamically (i.e. not through dialog resources), you will need to explicitly specify a runtime license key in the fc.Create(...) call. Contact us by email and let us know your order ID to get that key.
