title: How to sign my driver so it will install on Windows 7 64-bit?
body: <p>I have a kernel mode driver and I have to install t on 64 bit Windows&nbsp;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: <br/>
    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 testsigning 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 making it work on the 64 bit machine...</p>
