title: Invalid key name
body: <p>In a quick and dirty backup script that's been running fine for years, the registry backup part no longer works. I run the offending code in the command line and get the same result:</p>
  
  <pre><code>C:\&gt;reg export /y HKLM\SOFTWARE\ODBC\ODBC.INI test.reg
  ERROR: nombre de clave no válido.
  Escriba "REG EXPORT /?" para obtener detalles de uso.
  </code></pre>
  
  <p>Error translates as "invalid key name". If I lauch regedit and copy the key name to clipboard I get this:</p>
  
  <pre><code>HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI
  </code></pre>
  
  <p>If there is a typo, I'm unable to spot it.</p>
  
  <p>Am I really mistyping the key name? Is there any other reason for the error?</p>
