At a Windows 2000 or Windows XP workstation, browse to the location where you downloaded the ZfD 4 Support Pack 1, or insert the ZENworks for Desktops Program CD or the ZENworks 6 Desktop Management Program CD and run the winsetup.exe program to begin the installation.
Click the language you want to use for the installation. A window with general installation options will be displayed.
Click Install ZfD Middle Tier Server to launch the Middle Tier Server installation program.
Follow the prompts during the Middle Tier Server installation program to upgrade the ZfD Middle Tier Server files to ZfD 4 SP1 or ZfD 4.0.1.
NOTE: If you install NetWare 6 SP3 to a server where a previous installation of ZfD 4 already exists, the NetWare install will not copy new NetStorage file to that server. The ZfD 4 SP1 Middle Tier Server installation installs the current ZfD 4 SP1 files to the server.
If you have users who are accessing the myapps.html page on the Middle Tier Server through their Web browser, review the information below. Otherwise, continue with the next section, Upgrading the ZfD Management Agent .
ZfD 4 SP1 and ZfD 4.0.1 includes a new component, the ZfD installation manager. The installation manager controls the installation of the NAL plug-in files used with the myapps.html page. When a user accesses the myapps.html page on the upgraded Middle Tier Server, the installation manager is copied to and registered on the workstation. If a Windows NT/2000/XP user has restricted rights on the workstation, the operation will fail and the user will receive a plug-in install error.
There are several ways you can resolve this issue:
Perform an administrator installation: Log in to the workstation through an account with administrator rights and then access the myapps.html page on the upgraded Middle Tier Server to install the new files.
Continue to use the ZfD 4 NAL plug-in files: The ZfD 4 NAL plug-in files will continue to work with your upgraded ZfD Server and ZfD Middle Tier Server. Therefore, you can instruct users to access the older ZfD 4 myapps.html page on their workstation (c:\program files\novell\zenworks\nls\english\myapps.html) or you can replace the new myapps.html page on the upgraded Middle Tier Server with the old ZfD 4 myapps.html file. The ZfD 4 myapps.html page does not reference the new installation manager. Therefore, neither the ZfD installation manager or any of the new ZfD 4 SP1/4.0.1 NAL plug-in files will be installed.
This issue will also affect users who are running the ZfD Management Agent (not just the NAL plug-in) on their workstation. If you upgrade a restricted workstation to the ZfD 4 SP1/4.0.1 Management Agent and then the user accesses the myapps.html file on the upgraded Middle Tier Server, the new myapps.html page will initiate the download and registration of the ZfD installation manager. The operation will fail and users will be unable to access their applications through the myapps.html page.
