Can't Import Action Script into Adobe Acrobat DC

I'm having trouble importing a script I have been using into Acrobat previously.  Recently I was given an upgraded computer.  The name is unique and is not the same as any of the scripts already in the listt of scripts available in it Action Tools.

The Script is as follows:

---------------------------------------------------------------------------

<</Commands [/c << /0 [/c << /Config [/c << /UIPolicy [/i 3]

/HandlerName [/a /JavaScript]
/Params [/c << /ScriptCode [/t (this.extractPages\({nStart: 2, nEnd: 3, cPath: this.path.replace\("/.*\\/|\\.pdf$/ig", ""\)+"_propcov"+".pdf"}\);\r\n)]
