  4. Installation
  ======================================================================
     This section explains key steps for installing the critical patch.


     4.1 Installing
     ===================================================================
     To install:

     1. Copy the critical 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 critical 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 their original configuration.


     4.2 Uninstalling
     ===================================================================
     To manually roll back to the previous build:

     1. Locate the backup folder that the critical patch package created
        in the "\PCCSRV\Backup\CriticalPatch_B1433" 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.
