Attempting to save a PDF report throws an error.

Symptoms : 
 When attempting to create a PDF report on a tablet running Windows 8.1 an error message appears and no report is created. 
 
 
 Cause : 
 Windows 8.1 is missing some critical files the PDF creator relies on.  
 
 Solution : 
 Install the VC++ 2015 Redistributable files.  These are available at  www.microsoft.com . Use a search engine to find them. Choose the version that matches your tablet (32 or 64bit).  Install on the tablet. The PDF creation process should then work.
