Issue when migrating from FB 7 to FB 8  
  
In FB 7 it was quite legal to have expressions containing the predefined environment variable&nbsp;%Program Files (x86)%.  
In FB 8 this cause a parse error  
  
[Expression Error]: Expected . or % but got " ". [Program? Files]  
  
and the projects fails.  
If the&nbsp;%Program Files (x86)% is in an initial value for a global variable the project fails to open and fails to start.  
  
It is not backward compatible.&nbsp;

Hi   
  
 I have not been able to reproduce this here. Can you send the fb7 project file to [support@finalbuilder.com](mailto:support@finalbuilder.com) so we can see what is happening. If you are able to narrow it down to a small example tjat will make it easier to find the cause.
