     for this product, go to http://docs.trendmicro.com


  4. System Requirements
  ======================================================================
     You must install Worry-Free Business Security 10.0 before 
     installing this patch.     


  5. Installation
  ======================================================================
     This section explains key steps for installing the patch.


     5.1 Installing
     ===================================================================
     To install:

     1. Copy the patch executable file to a temporary folder, for 
        example, "C:\temp".

     2. Double-click the file. The modules are automatically copied to
        the correct destination.
      
     This patch installation package automatically rolls back the 
     Security Server to its previous configuration if there are
     problems during installation.

     If you encounter problems after installation, manually roll back 
     the Security Server to the original configuration.


     4.2 Uninstalling
     ===================================================================
     To manually roll back to the previous build:

     1. Locate the backup folder that the patch package created in the 
        "\PCCSRV\Backup\Patch_B1531" directory.

     2. Copy the backup modules to the original folders.

     3. Run the "TmTouch.exe" tool to trigger the hotfix 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.


  6. Post-installation Configuration
  ======================================================================
     No post-installation steps are required.

     NOTE: Trend Micro recommends that you update your scan engine and
           virus pattern files immediately after installing the product.
