  • Windows Presentation Foundation (WPF)

    Customers loading WPF applications that target SxS versions of the .NET Framework in a single process may experience crashes or unexpected behavior on stylus or touch enabled devices. This is sometimes seen when the Visual Studio Tools for Office add-in that is loaded is written in WPF.This error occurs because of a conflict between different versions of PenIMC.dll. This update addresses and fixes this issue.
