You need to get 64-bit ActiveX DLL files to work with the 64-bit version. Designtime Delphi is still always 32 bits.
If ChartFX does not support the 64-bit version, you are stuck. After reviewing the website, it seems that the supplier has not yet installed the 64-bit ChartFX ActiveX and is requesting feedback on how much demand there is.
I would recommend switching to TeeChart , which is Delphi's native code and has a very strong tradition on Delphi. You can be sure of future support for other platforms as they become available.
