title: Bootstrapper "Unable to read registry value"
body: <p>In boostrapper package.xml I am trying to read MSSQL entry from the regsitry like:</p>
  
  <pre><code>&lt;InstallChecks&gt;
      &lt;RegistryCheck Property="CheckSQLInstalled" Key="HKLM\SOFTWARE\Microsoft\Microsoft SQL Server" Value="SsrpActiveServer" /&gt;
  &lt;/InstallChecks&gt;
  </code></pre>
  
  <p>After I run the result setup.exe I get in the log:</p>
  
  <p><em>"Reading value 'SsrpActiveServer' of registry key 'HKLM\SOFTWARE\Microsoft\Microsoft SQL Server'
  Unable to read registry value
  Not setting value for property 'CheckSQLInstalled'"</em></p>
  
  <p>I run it as Administrator. UAC is off also...
  The path in registry is correct. I can even retrieve it with BAT file like:
      Reg query "HKLM\SOFTWARE\Microsoft\Microsoft SQL Server" /v SsrpActiveServer</p>
  
  <p>The problem happens on more than one machine. Any ideas?
  Thanks</p>
