Chatbox

For managed Chatbox updates, close the application before starting the installer: the update may fail with Exit Code 2 if the application is open. Add a pre-close, user-deferral, or retry step in Intune/ConfigMgr-style deployments before enforcing the update.

For managed Chatbox User-x64 updates, close Chatbox before launching setup. If the desktop app is open, the update can fail with Exit Code 2; close the process first and retry after detection confirms it has exited.

For managed Chatbox deployments, stage Microsoft Visual C++ v14 Redistributable (x64) before installing or updating the Windows package. The packaging deployment prerequisite for this app indicates installs or updates can fail when the prerequisite runtime is absent, so deployment detection should validate the runtime separately from the application install.
