Word Quits Unexpectedly When Using Multiple Add‑Ins on a Computer with a Touchscreen or Stylus

• What happens: While using Contract Tools and other Word add‑ins on a computer with a touchscreen or a stylus, Word quits unexpectedly (crashes).

• What this means: Because of a problem with Windows Presentation Foundation (WPF) and Microsoft software used on touch and stylus devices, Word may quit unexpectedly while using multiple Word add‑ins on tablet computers and similar devices if some add‑ins require .NET Framework 4 or later and others require .NET Framework 3.5 or earlier. (Contract Tools requires .NET Framework with a version between 4.5.2 and 4.8; to learn about other Contract Tools prerequisites, see Prerequisites for Installing Contract Tools.)

• What you should do: Disable add‑ins that require .NET Framework 3.5 or earlier. The documentation for your add‑ins should specify which version of .NET Framework they require. To learn how to disable a Word add‑in, see Disabling Word Add‑Ins. As an alternative, contact the developers of these add‑ins and ask them to update their add‑ins to require .NET Framework 4 or later.
