  • System.I.O.FileNotFoundException    or

This has been found in the Message Centre when trying to send an email and from the email hyperlink from the Patient Header - also when sending an email.


To fix, download and install  Visual C++ Redistributable Packages for Visual Studio 2013 -  install both x86 and x64
