title: Oracle Database installation error: environment path
body: <p>While attempting to install <strong>Oracle Database 11g Release 2</strong> on <strong>Windows 7 (64 bit)</strong>.</p>
  
  <p>Encountered following the error (<strong>PRVF-3929</strong>) </p>

  <p>It states that the environment variable path is too long. To reach this variable I searched "envir"  in Windows and selected "Edit variable settings for your account". Presumably it's the path of the system rather than user that must be changed.</p>

  <p>Can I delete at my discretion - naturally removing extensions will have a bearing on different language compilations. Why does Oracle demand this limit and is this specific to the install of Oracle or is it a permanent limitations of using oracle dbms?</p>
