title: Install CAB file from FireFox or command line
body: <p>I have a CAB file that contains a few DLLs, and an OCX ActiveX control, an OSD describing the contents, and an INF for installing the DLLs and ActiveX control.  These are coming from a 3rd party, so I can't control anything except how they are distributed to the client.</p>
  
  <p>They are being used within a Java applet, and they work cross browser, but only IE seems to support actually installing the CAB file.</p>
  
  <p>The installation is being done via:</p>
  
  <pre><code>&lt;OBJECT classid="clsid:actual-class-id-here" NAME="name"
          width="0" height="0" codebase="xxxx.cab#Version=w,x,y,z"&gt;
    &lt;param name="useslibrary" value="xxxx"&gt;
    &lt;param name="useslibrarycodebase" value="xxxx.cab"&gt;
    &lt;param name="useslibraryversion" value="w,x,y,z"&gt;
  &lt;/OBJECT&gt;
  </code></pre>
  
  <p>So, I need a way to install this CAB file that will work cross browser.  Since the above will only work via IE, I need an alternative, or I need a way to install it from the command line, which would be a reasonable workaround (I could then set up an installer to take care of it).  This needs to work on XP through Vista.</p>
  
  <p>Any help would greatly be appreciated!</p>
  
  <p>EDIT: <strong>Installing from command line would be much preferred</strong>, as then I could do a solution that isn't specific to IE, FireFox, or any other browser.</p>
