 4. Installation/Uninstallation
 =======================================================================
    4.1 Installation
    ====================================================================
    To install this Critical Patch:
  
    1. Copy the Critical Patch executable file to a temporary folder on
       the Worry-Free Business Security Server, for example, "C:\temp".

    2. Double-click the file. All Critical Patch modules are
       automatically copied to the correct destination.

    After the time stamp on the server files have changed, the server
    automatically notifies the Client/Server Security Agents to download
    the updated files.

    4.2 Uninstallation
    ====================================================================
    To roll back to the previous build:
   
    1. Locate the backup folder that the Critical Patch package created
       in the "\PCCSRV\Backup\CriticalPatch_B3221" directory.

    2. Copy any file that you want to roll back to the correct folder.

    3. Run the "TmTouch.exe" tool to trigger the hot fix mechanism.
  
       To run "TmTouch.exe": 
 
       a. Open a command prompt on the server.

       b. At the command prompt, browse to "PCCSRV\admin\utility\touch".
  
       c. Use the following syntax to run the touch tool:

          TmTouch.exe {filename}

          Note: {filename} is the file that you want to roll back.
  
          "TmTouch.exe" changes the file creation date to the current 
          system time.
