title: Why won't my batch files run since I changed a Windows "Environment Variable"?
body: <p>I had a couple of batch files to help me with minor tasks (one killed a running Skype process and the other deleted a file before running an executable). Both were only one or two lines of simple code.</p>
  
  <p>To run a program called Kernow I was told I needed to add a Windows environment variable called "Path" and set it to point to a Java folder (<em>C:\Program Files (x86)\Java\jre7\bin</em>) - the program wouldn't run until I had done this giving a Java error. </p>
  
  <p>I already had an environment variable called path which pointed to a long file path so instead of adding a variable I simply updated that one. </p>
  
  <p>Now neither of the batch files that were working fine before will work. Both will run with no errors but not produce results. </p>
  
  <p>I have very little knowledge of how batch files work with Windows. Can I set another environment variable called Path that will enable me to run my batch files <em>and</em> run Kernow??</p>
