[FieldTrip] Fieldtrip Problem ft_default

[Daniel Krauel]

 Subject: MCG

Dear community,

My name is Daniel Krauel  and I am working for the UKSH in Kiel Germany.
Currently I am analysing data of a MCG measurement. I am currently at the
fieldtrip version from  27.05.2017

I used fieldtrip to read and extract the datas and also for plotting of
sensor maps.It worked perfectly fine till one start. I couldn`t use
ft_defaults, only executing 2 lines add path and ft default to get the
error message below.

addpath('C:\Users\Daniel\Documents\MATLAB\Till_2\fieldtrip-20170527');
ft_defaults;

Undefined function or variable 'ft_platform_supports'.

Error in ft_defaults>checkMultipleToolbox (line 280)
if ~ft_platform_supports('which-all')

Error in ft_defaults (line 109)
  checkMultipleToolbox('FieldTrip',           'ft_defaults.m');

Can someone explain me how I fix this problem? It looks so easy because I
only execute two
lines but I can`t fix it.
I tried 4 different versions of fieldtrip and I also reinstalled matlab and
resets all settings.
In Addition the error message changes a little if I am using an other
version of fieldtrip.

Yours sincerly,

Daniel Krauel
