Don't know if this is the correct forum for this problem but would be obliged if anyone could help. When I switch on my computer I am receiving the following message: 'zHotkey.exe Unable To Locate Component: This application has failed to start because HKNTDLL.dll was not found. Re-installing the application may fix this problem.' I don't even know what this application is let alone how to re-install it. Can anyone help please?
