title: "Windows cannot verify the digital signature" for a driver I signed — what to do?
body: <p>I have a kernel mode driver and I have to install it on 64-Bit Windows 7. It needs to be digitally signed. I digitally signed it using the <code>dseo13b.exe</code>. But when I load the driver, I get an error in the system event log saying </p>
  
  <blockquote>
    <p>The driver failed to start due to the following error: Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.</p>
  </blockquote>
  
  <p>I don't want to use the test signing mode. How do I resolve this? Do I need to get a certificate from Microsoft?</p>
  
  <p>I have developed the driver and am now trying to make it work on the 64-Bit machine.</p>
