/M <num>

Launches several instances of the program, where <num> is the number of instances to be launched. Each instance will have its own settings. By default, you can launch one instance only.

"C:\Program Files\HotVirtualKeyboard\hvk.exe" /ACTION Win+K

Instructs the application to create the Log.txt file in the application folder (in the Data subfolder). The log file will contain details about the application's activity, which can be a helpful debugging aid.

The information contained in the log file is technical in nature and therefore not intended to be understandable by end users.

If a file with the specified name already exists in the application folder, it will be overwritten.


Instructs the application to create different log files for every startup. See the Data subfolder in the application folder.

You can also add the DWORD parameter EventLog=1 in the registry to do the same.


Enables the special mode for remote control devices. In this mode, you can use the arrow keys to move around the keyboard, and use Enter key to press the currently selected key.

Setup Command Line Parameters

The Setup program (HotVirtualKeyboardSetup.exe) accepts optional command line parameters. These can be useful to system administrators, and to other programs calling the Setup program.


Instructs Setup to be silent or very silent. When Setup is silent the wizard and the background window are not displayed but the installation progress window is. When a setup is very silent this installation progress window is not displayed. Everything else is normal so for example error messages during installation are displayed and the startup prompt is.

If a restart is necessary and the '/NORESTART' command isn't used (see below) and Setup is silent, it will display a Reboot now? message box. If it's very silent it will reboot without asking.


Instructs Setup to suppress message boxes. Only has an effect when combined with '/SILENT' or '/VERYSILENT'.


Prevents the user from cancelling during the installation process, by disabling the Cancel button and ignoring clicks on the close button. Useful along with '/SILENT' or '/VERYSILENT'.


Prevents Setup from restarting the system following a successful installation, or after a Preparing to Install failure that requests a restart. Typically used along with /SILENT or /VERYSILENT.
