N/A

Fix Information

Upgraded the MSXML library with the latest version 6.0 from Microsoft. This was an upgrade from MSXML2 to MSXML6 as the Microsoft team had asked us to do. So, basically, this will NOT directly address the Windows Defender blocking issue but the Microsoft team agreed to take an exception in Win Defender’s rule to allow the APM Web client to use ActiveX if the system is upgraded to MSXML6
