title: emacs 24 on windows 7, tramp cannot find plink program
body: <p>I am trying to use Emacs 24.2 with Tramp on windows 7 to remotely edit files on a linux server. I installed the Putty suit program and OpenSSH. I also placed the plink.exe in the putty suit into the bin folder under the emacs 24 folder, and added the folder emacs24/bin into the PATH environment variable.</p>
  
  <p>However, when I try to access the remote file from emacs with the command in the minibuffer: /username@host:filename, I get the following error message from emacs: plink is not recognized as an internal or external command. It seems that emacs cannot find the plink program. But, when I try to run plink in windows cmd, it can find the plink program. Also, I can ssh to the remote server in windows cmd. </p>
  
  <p>Can anyone tell me what's my problem? Do I need to install cygwin to make it work? Thanks a lot.</p>
