title: Windows 7 Access is Denied
body: <p>I'm trying to build the boost examples. I get the following error:</p>
  
  <pre><code>Access is denied.
  Access is denied.
  ...found 9 targets...
  ...updating 2 targets...
  gcc.compile.c++ bin\gcc\debug\hello.o
  Access is denied.

  <p>I'm not familiar with Windows 7, but I believe I have the correct access rights:

  <p>Can anyone shed some light on this error? Thanks.</p>
  
  <p>Update:</p>
  
  <p>Process Manager finds hundreds of non-SUCCESS results for bjam. A typical line, if it helps, has the properties:</p>
  
  <pre><code>Desired Access: Read Attributes
  Disposition:    Open
  Options:    Open Reparse Point
  Attributes: n/a
  ShareMode:  Read, Write, Delete
  AllocationSize: n/a
  </code></pre>
  
  <p>I'm not sure how to act on this though.</p>
