This utility requires the Lenovo files Keyboard_Core.dll and Contract_Keyboard.dll which are not included in this repository or software release for copyright reasons. If the program exits saying that one of these files is not found, locate the ThinkKeyboardPlugin folder on your computer - which should contain both files - and edit the following setting in the app.config:
<setting name="DllPath" serializeAs="String">
<value>C:\ProgramData\Lenovo\ImController\Plugins\ThinkKeyboardPlugin\x86</value>
</setting>
If you don't have this folder, either a) ensure you have the Lenovo utilities installed or b) panic.
This utility adds a system tray icon. Double click the icon to open the settings, or right click for a menu.
The project targets .NET 4.8 so you will need the .NET 4.8 Targetting Pack installed, or you can downgrade the target to an older framework.
