Inno Setup script help - selected drive D not working

[rfresh]

I'm trying to fix a bug in a script that I am using in the Inno Setup installer.

The problem is that when I select the drive D radio button (from a list of drive C, drive D) the script wants to always install on drive C.

I'm not that good at coding but in the GetDriveChoosed function, I saw that it was harded coded to always select drive C so I remmed out those lines but it still always selects drive C.

Can someone help me figure out what I need to do to modify the code so I can select any available drive on my system?

Thank you...

 
//get all drives letters of system
  drivesletters := StringOfChar( ' ', 64 );
  lenletters := GetLogicalDriveStrings( 63, drivesletters );
  SetLength( drivesletters , lenletters );
  drive := '';
  n := 0;
  while ( (Length(drivesletters) > 0) ) do
  begin
    posnull := Pos( #0, drivesletters );
   if posnull > 0 then
   begin
      drive:= UpperCase( Copy( drivesletters, 1, posnull - 1 ) );

      // get number type of disk
      disktype := GetDriveType( drive );

      // add it only if it is not a floppy
      if ( not ( disktype = DRIVE_REMOVABLE ) ) then
      begin
        SetArrayLength(DrivePrompts, N+1);
        SetArrayLength(DriveValues, N+1);
        SetArrayLength(DrvLetters, N+1);

        DrivePrompts[n] := drive + '  ' + DriveTypeString( disktype );
        DrvLetters[n] := drive;
        // default select C: Drive
        if ( drive = 'C:\' ) then DriveValues[n] := '1';
        n := n + 1;
      end
  drivesletters := Copy( drivesletters, posnull+1, Length(drivesletters));
  end
end;


function GetDriveChoosed : String;
var i:Integer;
begin
  for i:=0 to GetArrayLength(DriveValues)-1 do
    begin
      //if DriveValues[i]='1' then
      //  begin
          Result:=DrvLetters[i];
          Exit;
      //  end;
    end;
  Result:='?';
end;

I'm no expert with inno setup and I'm fairly sure you haven't shown us the complete script but I think the problem might be that you've remmed out the if statement in GetDriveChoosed. That function is always going to return the first drive found.

BTW, I've deleted your other thread as it was a duplicate of this one.
