title: Jar file won't run on double click
body: <p>I know you may blame me for this being a dupe - but frankly, I do not know what to do next. I spent hours online trying to find my solution, and have found nothing. Zilch. Zero.</p>
  
  <p>Anyway, this is my problem: when I double click my runnable jar file, it shows a hourglass cursor for a second and then it disapears, leaving me with nothing. I have re installed my JDK and JRE 2 times, and nothing happens. Here is my manifest file:</p>
  
  <pre><code>Manifest-Version: 1.0
  Class-Path: .
  Main-Class: gedr.proj.Paint.Frame
  </code></pre>
  
  <p>I have tried to run my application via the  command line, but am baffled by how to do it.</p>
  
  <p>Tell me if you need any more information, or tell me what to do. Thanks in advance</p>
  
  <p>EDIT: If I try 'java -jar PaintV2.jar' in cmd, it returns</p>
  
  <pre><code>Error: Unable to access jarfile PaintV2.jar
  </code></pre>
  
  <p>when I run 'ftype | find "jarfile"' it returns</p>
  
  <pre><code>jarfile="C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*
  </code></pre>
