When I just type "winecfg", this is the result I get:
dick@dick2:~$ winecfg
+ cd /home/dick/Videos
+ seconds=0
+ echo 0
+ ffmpeg -loglevel warning -y -t 0 -i -d-.mp4 -d-out.mp4
Unrecognized option 'd-out.mp4'.
Error splitting the argument list: Option not found
dick@dick2:~$ wine winecfg
(GUI applears and works.)
