Multiple issues running grunt.cmd on windows
I had to modify grunt.cmd because the path for my system was very wrong:
Originally:
 %~dp0Application Datanpmnode_modulesgrunt 
Which would print:
 dacwnasProfiles<user>Application DatanpmApplication Datanpmnode_modulesgrunt 
 Running grunt.cmd would throw a cannot find module error.  Changing it to %~dp0node_modulesgrunt" removes the error.  
 But, running grunt.cmd --version in windows outputs nothing.  It simply pauses for a moment and returns to a blank command line.  
I'm running Windows 7 64-bit, and the command line is run as administrator
 First, you should have the grunt-cli package installed globally:  
npm install -g grunt-cli
 Next, make sure you have grunt installed in your project folder.  
You can do this by:
grunt is part of your package.json and run: npm install  npm install grunt  After this, you shouldn't have any trouble running Grunt.
Did you install grunt-cli?
My grunt.cmd content looks like that:
:: Created by npm, please don't edit manually.
@IF EXIST "%~dp0node.exe" (
  "%~dp0node.exe"  "%~dp0node_modulesgrunt-clibingrunt" %*
) ELSE (
   node  "%~dp0node_modulesgrunt-clibingrunt" %*
)
