All rights reserved. ____________________________________________________________________ CONTENTS 1. System Requirements 2. Installing the GO-Global Host 3. Running the Cluster Manager 4. Known Issues 5. Upgrading GO-Global ------------------------------------------------------------------- 1. SYSTEM REQUIREMENTS ------------------------------------------------------------------- 1.1 GO-Global Host The GO-Global Host requires one of the following Windows operating systems: * Windows Server 2008 Standard or Enterprise with Service Pack 2 (x86 and x64) * Windows Server 2008 R2 Standard or Enterprise (x64) * Windows Server 2003 R2 Standard or Enterprise Edition (x86) * Windows Server 2003 Standard or Enterprise Edition with Service Pack 2 (x86) * Windows 7 (x64) * Windows Vista with Service Pack 2 (x86 and x64) * Windows XP Professional with Service Pack 3 (x86) Where applicable, these platforms are supported with or without the Security Rollup Package. Right-to-left languages are not supported. Only the above versions of Windows are supported. GO-Global cannot be installed or run on other versions of the Windows operating system. GO-Global includes support for WoW64 (“Windows 32-bit On Windows 64-bit”) which allows 32-bit applications to run on the x64 versions of Windows. You must have administrative rights on the host to perform the installation and the server must have TCP/IP as a network protocol. A Web server must also be available in order to set up the server for browser deployment. GO-Global supports a maximum round-trip latency of 500 milliseconds. The minimum memory requirement for a GO-Global Host is 2 GB. 1.2 GO-Global Clients GO-Global supports the following platforms: * Windows 7, Windows Vista, Windows XP, Windows 2000, Windows Server 2003, Windows Server 2008. With the exception of Windows 2000, which is 32-bit only, both the x86 and x64 versions of these operating systems are supported. * Red Hat Linux (Enterprise Linux 4 and 5) and SUSE Linux (Enterprise Desktop 10.) Only a 32-bit client is provided. When installing this client on a 64-bit operating system, additional 32-bit dependencies may need to be installed. Consult your distribution's documentation for details on how to do this. Installing the client via a meta-packager such as yum will automatically fetch and install these dependencies for you. * Mac OS 10.3 and later. * Pocket PC 2003 and Windows Mobile 5. * Windows CE 4.2 or later on Mitsubishi's TX120 device and Mintwave's ACC-Lite and ACC-mini devices. SEH (the C++ Structured Exception Handling component) and RTTI (the Run-Time Type Information component) are required to run GO-Global on a Windows CE device. To determine if these components exist on the device, open ceconfig.h found in the Windows folder. On a Windows CE 4 device, if the following lines are included in this file, RTTI and SEH are supported. #define COREDLL_CRT_RTTI 1 #define COREDLL_CRT_CPP_SEH 1 On a Windows CE 5 device, if the following line is included in this file, RTTI and SEH are supported. #define COREDLL_CRT_CPP_EH_AND_RTTI 1 GO-Global supports the following browsers: * Apple Safari 2.0.4 and later * Mozilla Firefox 3.0 or later * Internet Explorer 6.0 or later Clients must have TCP/IP as a network protocol. ------------------------------------------------------------------- 2. INSTALLING THE GO-GLOBAL HOST ------------------------------------------------------------------- GO-Global is delivered as a self-extracting executable and can be installed by double-clicking the executable. It can also be unpacked and installed by running gg-host.windows_x86.exe or gg-host.windows_x64.exe.exe in the root folder where it was unpacked. The setup installs all of the GO-Global Host files as well as the files necessary to configure the GO-Global Host for browser deployment. ------------------------------------------------------------------- 3. RUNNING THE CLUSTER MANAGER ------------------------------------------------------------------- The Cluster Manager allows administrators to add and remove applications and to administer, monitor, and control client access to the GO-Global Host. >> To run the Cluster Manager Double-click the Cluster Manager icon on the desktop. -or- 1. Click the Start button on the Windows taskbar. 2. Click Programs | GraphOn GO-Global 4 | Cluster Manager. Applications must be registered with the Cluster Manager before clients can access them. >> To register an application with the Cluster Manager 1. Click the Applications tab. 2. Click the Add button. 3. Browse for the application’s executable path. ------------------------------------------------------------------- 4. KNOWN ISSUES ------------------------------------------------------------------- GO-Global for Windows 3.2 Clients cannot connect to GO-Global 4 Hosts, and GO-Global 4 Clients cannot connect to GO-Global for Windows 3.2 Servers. GO-Global does not support Group Policy logon or logoff scripts. Microsoft's VBScripts are not supported as logon scripts unless they are run in a batch file. Client-side password caching does not work when GO-Global is configured with a hardware load-balancer. Running the Browser Plug-in for Mac OS X in embedded windows mode, when logged in as root, is not supported on GO-Global. Using the Right-Control - Alt - Delete keyboard combination in Microsoft Excel is not supported. Redirecting the location of a user’s profile (e.g., the Application Data folder) through GO-Global is not supported. GO-Global loads the user's profile before applying Group Policy because the user's registry hive has to be loaded before Group Policy is applied. Copying a file on a GO-Global Host and pasting it to the client, while attempting to overwrite an existing file, may not work. GO-Global does not support Parallels Virtuozzo. When a user's password has expired or is about to expire, the Change Password warning dialog appears behind the Sign In dialog. The user must move the Sign In dialog in order to see the Change Password warning dialog. GO-Global supports Adobe Acrobat 8.0 in a GO-Global session. Previous versions of Acrobat are not supported. Apple's Preview application is not supported when printing from a Mac. Adobe Reader is required in order to print when running the Mac OS X Client or the Browser Plug-in for Mac OS X. Japanese keyboards are not supported on Mac OS X. Windows Explorer is not displayed when clicking Explore or Open, from within a File Open dialog of an application running in a GO-Global session. When users running the Windows CE Client print to client printers, squares appear between words instead of empty spaces. This is a Microsoft PDF Viewer bug, not a GO-Global for Windows bug. Client sounds may also play on the GO-Global Host. Painting problems may occur if a client's Task Manager is set to "Always On Top". GO-Global's License Manager operates by using a file called "license.lic". This file can be edited, but in doing so, can be made invalid. The contents of this file, therefore, should not be modified. If a user can successfully log on to a GO-Global Server, but no applications are listed in the Program Window, the license file may be invalid. If a GO-Global Host experiences low-memory conditions, defined as either less than 2000 available system page table entries or less than 20 MB of available physical memory, the Logon Manager will display the following messages, respectively: "Logon failed. System page table requirement was not met," and "Logon failed. Physical memory requirement was not met." Colors may display incorrectly when the client's display is set to 256 colors. Journal record hooks are not supported. As such, macros may fail to record in some applications. On Macintosh, the "busy" cursor may be displayed in place of the arrow cursor. No error message is displayed if a user has insufficient rights to install the ActiveX Client. When running the Windows Client or when running a GO-Global client in loose windows mode via a Web browser, application windows may fail to come to the foreground when clicking on their associated taskbar item. If this occurs, click on any exposed area of the desired window to bring it to the foreground. The cut and paste shortcut keys (Apple+C and Apple+V) do not work properly on the Macintosh. Use CTRL+C for copy and CTRL+V for paste instead. OLE objects embedded in a client-side file cannot be edited. If the application required to edit the OLE object is available on the host, copy the file to a drive on the host, edit it, and then, if desired, copy it back to the client. Data copied to the clipboard from an application deployed via GO-Global is cleared when a client session is disconnected. Applications running in GO-Global sessions are displayed using 16-bit color. When Integrated Windows authentication is enabled in the Cluster Manager, items on mapped drives will only be displayed in the Program Window when the machines are configured on an Active Directory network. Active Directory networks are not supported on NT systems or domains. When a GO-Global Host is connected to a relay server, no warning is displayed that the host's settings (published applications, etc.) will be replaced by those of the relay server. When Integrated Windows authentication is used to authenticate a user on a Windows NT domain, the user will be unable to access computers on the domain other than the host. In this case, users should be able to access network resources after entering their user name and password. (Note: This problem does not occur if the host computer is a member of an Active Directory, and in this case, users are not required to enter their user name and password to access network resources.) On GO-Global Hosts running Japanese Windows Server 2003, IME does not appear on the client when the Windows Server 2003 box is locked by the operating system. Users are unable to reconnect to a disconnected session while the session is being shadowed. GO-Global does not support running the Application Publishing Service in any account other than the System account. The keyboard mapping command-line argument -kb is case sensitive on the Linux Client and the Mac OS X Client. -KB will not work. GO-Global does not support the /3GB switch. PDFCreator from pdfforge is not supported. Microsoft's XPS Document Writer is supported as a client printer when using the Universal Printer Driver, but not the XPS Printer Driver. In 32-bit GO-Global environments, users are unable to create a new session when Avast Free Antivirus 5.0 is installed on the GO-Global Host. To avoid this, disable the "Behavior Shield" feature in Avast AntiVirus, located under Realtime shield | Behavior shield | Stop. The 64-bit GO-Global Host software can be installed on a system with VMWARE 7, but not VMWARE 6. Automatic client updates are not available to users running the GO-Global Client with Internet Explorer 6. ------------------------------------------------------------------- 5. UPGRADING GO-GLOBAL ------------------------------------------------------------------- When upgrading from GO-Global for Windows 3.2, running the GO-Global 4 Host installer automatically uninstalls version 3.2 and backs up existing GO-Global settings, including the list of published applications and host options. These settings are fully restored during the 4.0 installation. A new license is required to run the 4.0 host. Customers who are not current must contact their local reseller or sales@graphon.com. When GO-Global 4 is installed on a computer that does not have GO-Global for Windows 3.2 installed, the idle timeout is enabled and set to 30 minutes. This is different than GO-Global for Windows 3.2, where the idle timeout is disabled by default. Cluster Managers on computers running GO-Global for Windows version 3.2 are unable to display or administer GO-Global 4 Hosts, and vice versa. GO-Global Hosts running different versions of GO-Global do not recognize each other.
