In Finalbuilder 6 I perform a Read XML to variable.&nbsp; It is set for Highest Available.&nbsp; Moving the same project and migrating to Finalbulder 7, I get an error

Error parsing xml file - reason: DTD is prohibited.  
, source text: \<!DOCTYPE msi [  
&nbsp;

To work around it I switch the MSIXML Parser setting from Highest Available to MS&nbsp;XML 4.&nbsp; This used to work fine in Finalbulder 6.

In FinalBuilder 7, Use Highest available will use MSXML 6 if installed. It looks like they changed the default for the ProhibitDTD property in 6.0 - [http://msdn.microsoft.com/en-us/library/ms762632(v=VS.85).aspx](http://msdn.microsoft.com/en-us/library/ms762632(v=VS.85).aspx)   
  
 We’ll add an option for this so you can control the property.
