Cannot open Font .ttf with ShellExecuteW

[Mpower]

Dear Coders,

I can open text files, videos, images,  but not Font files ".ttf ".  I would like to open it first, then install. Is there a trick to open them ?

Thank you in advance for your support,

#import "shell32.dll"
int ShellExecuteW(int hwnd, string lpOperation, string lpFile, string lpParameters,string lpDirectory, int nShowCmd);
#import

string FileName = "SPORT.ttf";

int init()
  {
   ObjectsDeleteAll(0,"BUTTON")
   ;
   return(0);
  }

     {
      if(sparam=="BUTTON")
        {
         OPEN();
        }
     }
  }

1. You do not open them, you install it into Windows and then that font can be selected in text operations.
2. Shell only can start executables - .exe .com.

Thank you William Roeder for your prompt reply  ;)

I continue to look for the way how to install Font programmatically with MT4. I mean open the window, then we just click on Install.

Have a great day,
