Real-Time Windows Target

Uninstalling the Kernel

If you encounter any problems with the Real-Time Windows Target, you can uninstall the kernel. The kernel executable file remains on your hard drive so that you can reinstall it:

1. In the MATLAB command window, type

• rtwintgt -uninstall
  

1. MATLAB displays the message

   • You are going to uninstall the Real-Time Windows Target kernel.
     Do you want to proceed? [y] : 
     

2. To continue uninstalling the kernel, type

• y
  

1. MATLAB uninstalls the kernel by removing it from memory and displays the message.

   • The Real-Time Windows Target kernel has been successfully 
     uninstalled.
     

3. To check that the kernel was correctly uninstalled, type

• rtwho
  

1. MATLAB should displays the following message
   
   

   If you are running Windows 98, you need to reboot your computer before the uninstall is complete.

   Once uninstalled, the kernel is no longer active, and has no impact on the operation of your computer.

There are two additional ways to uninstall the Real-Time Windows Target kernel. They are useful if you uninstall MATLAB before you uninstall the kernel.

From the Start menu select Settings, Control Panel, and Add/Remove Software. Choose Real-Time Windows Target to uninstall the kernel.

Alternately, from the DOS prompt of your computer, type

• rtwintgt -uninstall
  

and the kernel will uninstall from your system. Typing

• rtwintgt -forceuninstall
  

forcibly deregisters the kernel from the operating system without deleting any files. This option should only be used when all other attempts to uninstall the kernel fail. This command can be used both within MATLAB and at the DOS prompt.
