Hello Rob

I'm not familiar with Windows or the IDE you're using, but the error  
indicates to me that the tool is not finding the boost/regex headers.  
Do you see an error message 'File not found' associated with the  
header include? Do you have your boost home directory in your include  
path however your IDE does it?

Cheers

Mike
