1. May we know what is this critical update about?
   • One of our technology partners inadvertently applied a date-related mechanism in their software.  We discovered this a recently and have been working diligently with that partner to create the most seamless update experience possible.
2. What happens if the patch is not applied before 17th Jul?
   • Conversions using the IE engine will fail. 
3. One of the perquisites for this critical patch is we are using any version of WebGrabber from 2013 R1.0 to 2016 R2.0 our webgrabber is 2013.2.2.16089
   • WG 2013 R2.2 is included in the versions affected
4. For the other perquisite.  You mention that we will need to apply this fix if the Internet Explorer (IE) Engine for conversions is used.  May I know which .net dll reference or namespace that you are referring?  Best if you can provide some sample code for the IE engine.
   • oWG.EngineToUse = APWebGrabberInterface.ConversionEngine.IE;   //IE engine use in .NET
   • oWG.EngineToUse = 1   ‘ IE engine use in COM, 0 = Native, 1 = IE
   • If the EngineToUse is not explicitly stated in the code, then it is defined in the Configuration manager. See attached image.
   • Note that the source code overrides the Configuration Manager, so check the source code first. 
5. Can we do a further test after setting the system date to a future date?  
   •  Yes
6. Last but not least, where we can download the critical update from?  Thanks.
