:set diffexpr?
diffexpr=MyDiff()

then I put the line:
echo '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' . arg3 . eq

before this in the _vimrc (copied from vimrc_example.vim):
silent execute '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' .
arg3 . eq

:vert diffsp vimrc~
!""C:\Program Files (x86)\Vim\vim74\diff" -a --binnary
C:\Users\Marcio\AppData\Local\Temp\VIo4C8B.tmp
C:\Users\Marcio\AppData\Local\Temp\VIn4C8C.tmp >
C:\Users\Marcio\AppData\Local\Temp\VId4C8D.tmp"
E810: Cannot read or write temp files
E97: Cannot create diffs

I just remove the MyDiff() function from _vimrc then the diff works!
It is Ok for me, but is there a failure in the Vim instalation?
