FNC Core Install

I have successfully installed web core and want to use the additional functionality in FNC but I can't get it installed. Installation fails every time with messages about a path is too long. I have researched this and tried the suggested solutions but still no luck. Is there some sequence that this needs to be installed?

Delphi 11.3, Windows 11

Please check if the RAD Studio library path doesn't contain additional backslashes or paths that are no longer used and clean them up. Then try again.
