2.13. Nothing happens when you run K1000; does not open

Last Updated: Feb 2019

Applies to supported versions of Kurzweil 1000


You attempt to run or open Kurzweil 1000 and nothing happens. An entry in the Windows Task Manager may not even appear momentarily.

This problem may occur if Windows 10 Defender Antivirus is enabled with Controlled folder access, and Controlled folder access somehow incorrectly flagged Kurzweil 1000 or components of Kurzweil 1000 as unsafe.


Disable Windows Defender and/or disable Controlled folder access, and/or add Kurzweil 1000.exe and the C:\Program Files (x86)\Kurzweil Educational Systems folder as Exclusions to scan, active protection and controlled folder access components of Windows Defender.
