When I enter this line:
$ convert wide.png -crop 750x100+$i+0 +repage "%02d"$i.png
  it gives me the error:
Invalid Parameter - -crop

What ImageMagick version? IIRC -crop is a recent addition.

If that works then you are using IM version 7 Is this in linux or Windows ? Obvously bash for linux, you need an equivalent  bat file for Win. I am really rusty with Windows batch when it comes to loops.  For IM 7 exchange magick for convert (convert is also a Windows command that plagues Windows users)

I am using cygwin, I believe that is a "linux" emulation terminal for windows.  I installed the imageMagick version ImageMagick-i686-pc-cygwin.tar.gz for cygwin.  I downloaded that file within cygwin (wget) tar and installed in the cygwin environment. 

$ magick -version
