Visualizador de PDF do LaTeX do Vim?

Question

Tentei alterar o padrão DVI da viseira do vim-latex para a viseira do pdf. Eu quero colocar o leitor de PDF da Adobe, então eu mudei o arquivo _vimrc :

source $VIMRUNTIME/vimrc_example.vim

set diffexpr=MyDiff()
function MyDiff()
  let opt = '-a --binary '
  if &diffopt =~ 'icase' | let opt = opt . '-i ' | endif
  if &diffopt =~ 'iwhite' | let opt = opt . '-b ' | endif
  let arg1 = v:fname_in
  if arg1 =~ ' ' | let arg1 = '"' . arg1 . '"' | endif
  let arg1 = substitute(arg1, '!', '\!', 'g')
  let arg2 = v:fname_new
  if arg2 =~ ' ' | let arg2 = '"' . arg2 . '"' | endif
  let arg2 = substitute(arg2, '!', '\!', 'g')
  let arg3 = v:fname_out
  if arg3 =~ ' ' | let arg3 = '"' . arg3 . '"' | endif
  let arg3 = substitute(arg3, '!', '\!', 'g')
  if $VIMRUNTIME =~ ' '
    if &sh =~ '\<cmd'
      if empty(&shellxquote)
        let l:shxq_sav = ''
        set shellxquote&
      endif
      let cmd = '"' . $VIMRUNTIME . '\diff"'
    else
      let cmd = substitute($VIMRUNTIME, ' ', '" ', '') . '\diff"'
    endif
  else
    let cmd = $VIMRUNTIME . '\diff'
  endif
  let cmd = substitute(cmd, '!', '\!', 'g')
  silent execute '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' . arg3
  if exists('l:shxq_sav')
    let &shellxquote=l:shxq_sav
  endif
endfunction

execute pathogen#infect()
set number

" REQUIRED. This makes vim invoke Latex-Suite when you open a tex file.

set shellslash

" OPTIONAL: This enables automatic indentation as you type.
filetype indent on

" OPTIONAL: Starting with Vim 7, the filetype of empty .tex files defaults to
" 'plaintex' instead of 'tex', which results in vim-latex not being loaded.
" The following changes the default filetype back to 'tex':
let g:tex_flavor='latex'


" to get default compile to pdf
let g:Tex_DefaultTargetFormat = 'pdf'
let g:Tex_MultipleCompileFormats='pdf, aux'
let g:Tex_ViewRule_pdf = 'AcroRd32'

Eu escrevi:

" to get default compile to pdf
let g:Tex_DefaultTargetFormat = 'pdf'
let g:Tex_MultipleCompileFormats='pdf, aux'
let g:Tex_ViewRule_pdf = 'AcroRd32'

e do vim com o comando \lv apenas imprime: call texViewLatex()

Portanto, defino PATH (estou usando o Windows) e adicionei:

C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe

e nada mudou! Não mostra o arquivo PDF quando eu coloco \lv .

O que devo fazer?
