According to the Server Requirements for Symantec ICA section of the Symantec ICA Administrator Guide, Information Centric Analytics' (ICA) Internet Information Services (IIS) server requires Visual C++ Redistributable Packages for Visual Studio 2013 (x64). Per Microsoft, this version is no longer supported:
Will ICA still be in a supported state if the Visual C++ Redistributable Packages for Visual Studio 2013 (x64) package is upgraded to Visual C++ Redistributable Package v14.42.34433.0 or later?
Version : 6.x
Component : Microsoft Internet Information Services (IIS)
ICA's dependency on the Visual C++ Redistributable Packages for Visual Studio 2013 (x64) will be replaced with a dependency on the Visual C++ Redistributable for Visual Studio 2015-2022 (x64) package with the release of version 6.7 MP1.
