Note that this version is a 16-bit program and therefore you do not need to have Win32s(R) installed on your computer. This release includes Microsoft Windows 3.1 Virtual Machine (VM) for Java(TM). It supports the same feature set available in Sun JDK 1.02. - To run the browser only: - 4 MB, 386 processor required; 8 MB, 386 recommended - To run the browser and Java VM: - 8 MB, 486 required; 12 MB, 486 recommended - Microsoft Windows 3.1 or 3.11 or Microsoft Windows for Workgroups 3.1 or 3.11 - A VGA monitor or better - A mouse - A 9600 BPS modem or a LAN connection - TCP/IP Stack & Dialer, or configured connection for Windows NT 3.51 Important A TCP/IP network protocol stack and a dialer (often referred to as Winsock.dll) are required to access the Internet through an Internet service provider (ISP). As mentioned above, this version of Internet Explorer requires that these components be installed before running Internet Explorer. If you are accessing the Internet through a LAN or just browsing your internal network (intranet), your network administrator can provide you with the appropriate version of Winsock.dll. Note If you are running NT 3.51, the service pack 4 is needed. Otherwise, you will see instability in the VM. -------------------------------------- INSTALLING MICROSOFT INTERNET EXPLORER -------------------------------------- Installing from the Internet ---------------------------- To install Microsoft Internet Explorer from the Internet, carry out the following procedure. Important For the 40-bit version of Internet Explorer, the name of the download file is Dlmin30f.exe. For the 40-bit Windows NT version, the file name is MinNT30f.exe. For the 128-bit version, you determine the file name at the time you download it. 1. Create a temporary directory on your computer. 2. Choose to download Microsoft Internet Explorer from the Internet, and save the download file to the temporary directory. 3. In File Manager, run the download file to extract the program files. 4. Read the instructions below for LAN installations and for installing with existing TCP/IP connections. 5. In File Manager, run Setup.exe. Setup installs files in the directory you specify. Note If you are upgrading to a newer version of Internet Explorer and choose to install the program in a different directory from your original version, please refer to the following section, "Upgrading over Earlier Versions," for further instructions. 6. Run Internet Explorer. Upgrading over Versions 1.5 and 1.6 Beta If you are upgrading from the version 1.5 or version 1.6 beta, please read the following special notes. - The format of Iexplore.ini has changed, so Setup will make a backup copy of your current Iexplore.ini file to a file called Ie16ini.sav. - You will need to reapply any user-selectable settings, such as proxy servers, in the new version. - Your Favorites and History lists will be preserved. - Win32s is not required for this version, so if you installed Win32s specifically to run the version 1.6 beta, then you can remove it from your system. Please refer to the following URL for instructions on removing Win32s from your system: http://www.microsoft.com/kb/faq/devtools/winsdk/win32s/faq3476.htm LAN Installations ----------------- After completing the steps outlined above, you should be ready to use Microsoft Internet Explorer over your LAN. You will be able to use Internet Explorer to browse the Internet. (If you are not sure whether you currently have access, consult your network administrator.) If you have access, your LAN administrator should provide you with proxy servers that also can be used. To install Internet Explorer, make sure you have the TCP/IP protocol installed. Proxy servers can also be used, provided they are CERN compliant. To enable use of a proxy server: 1. On the View menu, click Options. 2. On the Connection tab, select the check box under Proxy Server, and then click Settings. 3. In the Proxy Settings dialog box, type the address of your proxy server and change any other necessary settings. Running on a Remote Installation -------------------------------- If you will be running Internet Explorer on a diskless workstation: 1. Install Internet Explorer on the server. 2. Copy Iexplore.ini to the client Windows directory. If you will be sharing a remote installation from a client computer running Windows 3.1: 1. The following files must be in the client computer's Windows\System directory: Comctlie.dll Vscrpt16.dll Jscrpt16.dll Secur16.dll Security.dll Msapsp16.dll Msnssp.dll Signin16.hlp Msnath16.hlp and optionally the following RealAudio files: Ragui16.dll Ra16.dll Ract14_4.dll Ra3228_8.dll Pnloader.dll 2. The client computer must have OLE 2.03 or higher installed. Copying the OLE files will not properly update the syustem. 3. The file Iexplore.ini should be on the client computer. Using Third-Party Telnet Helper Applications ---------------------------------------------- To configure Internet Explorer to use a Telnet helper application, open Iexplore.ini and locate the [Helpers] section. Remove the semicolon (;) from in front of the telnet= line, and type the path to the telnet application. For example: [helpers] telnet=c:\windows\telnet.exe %s Installation with Existing TCP/IP Connections and ISP Accounts -------------------------------------------------------------- In general, all that is required is that you configure the PATH command in your Autoexec.bat file so that Microsoft Internet Explorer can find the Winsock.dll file you are using to connect to the Internet. For example, if your Winsock.dll file is in the directory C:\Connect, add a line directly under your current PATH command that reads: PATH=%PATH%;C:\CONNECT If you have multiple Winsock.dll files, please make sure that the Winsock file you choose to use comes first in the PATH command or is located in the directory where your browser files reside. Following are procedures for installing Microsoft Internet Explorer over some common Internet access products. Other packages available include FTP Software, Network TeleSystems, and shareware from Trumpet Software (http://www.trumpet.com.au/wsk/winsock.htm). Internet Chameleon 4.5 ---------------------- 1. Install Microsoft Internet Explorer to the suggested default directory (C:\Iexplore). 2. Make sure that the Internet Chameleon directory is in your path. If it is not, add it to the PATH statement in your Autoexec.bat file, and then restart your computer. 3. Run the Internet Chameleon dialer program (from the Custom icon). 4. Select the line corresponding to your current Internet service provider, and make sure that the Dial On Demand command on the Setup menu has a check mark by it. This makes the dialer program run when Internet Explorer tries to connect to the Internet. 5. Start Internet Explorer by double-clicking the Internet Explorer icon in the Microsoft Internet Explorer group in Program Manager. If you have configured the Chameleon dialer to dial on demand, an Internet connection is made when you first enter an Internet address in Internet Explorer. If you have not configured the Chameleon dialer to dial on demand, you need to start that program before you start Internet Explorer. Netscape Navigator 1.2 Personal Edition --------------------------------------- 1. Install Microsoft Internet Explorer to the directory that contains your Netscape Navigator files. For example, if you installed the Netscape browser in the default directory (C:\Netscape), place the Internet Explorer files in the same location. 2. Run Internet Explorer. Other Internet Dialer Packages ------------------------------ 1. Install Microsoft Internet Explorer to the suggested default directory. 2. Make sure that the Internet dialer directory is in your path. If it is not, add it to the PATH statement in your Autoexec.bat file, and then restart your computer. 3. Run your existing Internet dialer program. 4. Choose to enable dial on demand (if your dialer supports this option). This makes the dialer program run when Internet Explorer tries to connect to the Internet. 5. Start Internet Explorer by double-clicking the Internet Explorer icon in the Microsoft Internet Explorer group in Program Manager. If you have configured the dialer to dial on demand, an Internet connection is made when you first enter an Internet address in Internet Explorer. If you have not configured the dialer to dial on demand, you need to start that program before you start Internet Explorer. Making a Backup Copy of the Software ------------------------------------ 1. Make sure that you have two floppy disks (3.5" disks with 1.44 MB capacity). 2. After you have downloaded the software and have run the download file (see "Installing from the Internet" earlier in this file) your temporary directory contains all the files that you need to make disks. 3. Copy the file Iew31_3.cab on your disk number 3. 4. Copy the file Iew31_2.cab on your disk number 2. 5. Copy the following files on your disk number 1. Files.inf Readme.txt Iew31_1.cab Setup.exe Install.lst License.txt Install.bin Setup.ini Changing the Default Installation Directory ------------------------------------------- Setup enables you to change the name of the installation directory for Microsoft Internet Explorer. The default directory name is C:\IExplore. If you choose to install Microsoft Internet Explorer in a different directory, please make sure the new directory name does not contain any special extended or DBCS (Double-Byte Character Set) characters. Only characters in the lower ASCII range can be used for the name of the installation directory. ------------ VM FOR JAVA ------------ This release includes Microsoft Windows 3.1 Virtual Machine (VM) for Java(TM)*. It supports the same feature set available in Sun JDK 1.02. At least 8 MB is required to run Java. Note If you are running NT 3.51, the service pack 4 is needed. Otherwise, you will see instability in the VM. How to Disable the VM for Java ------------------------------ To disable Java applets in Internet Explorer because of security or other concerns, carry out the following steps: 1. Click the View menu, and then click Options. 2. Click the Security tab. 3. Clear the Enable Java Programs checkbox. Settings for Java ------------------ The settings for VM for Java are in the JavaVM section in the Iexplore.ini file, which is located in the Windows directory. You can modify the following settings by using a text editor, such as Notepad, to open the file. ClassPath: Lists which directories to search for classes. If you want to run Java applets on your local computer, you can put all the class files into an uncompressed Zip file and add the full path of the Zip file to your ClassPath string. For example: ClassPath=c:\iedir\classes.zip;c:\myclass\myclass.zip DefaultOptions: The options for Java VM mx Sets the maximum Java heap size. ms Sets the minimum Java heap size. ss Sets the C stack size of the VM. oss Sets the Java stack size of the VM. verify Verifies all classes when read in. verifyremote Verifies classes reading in over the network (default). noverify Does not verify any class. Typically, you do not need to change the default options settings. However, if you have problems running large and complicated applets (which include many classes and need more heap space), try increasing the numbers for the ms and mx settings. By default, ms is set as 600KB and mx is set as 2048KB. You can increase the number of the ms option to 800KB or so; or, increase mx to 3096KB or so. However, ms should not be larger than mx. You can try this when you see an Out Of Memory exception on the browser status bar. *Java is a trademark of Sun Microsystems, Inc. Technical Support for VM ------------------------ VM for Java is supported through the Microsoft News Server. The following newsgroup is dedicated to the discussion of VM for Java and provides a great deal of support: news://msnews.microsoft.com/microsoft.public.java.win16.all Note For general discussion of Internet Explorer, use this newsgroup: news://msnews.microsoft.com/microsoft.public.internetexplorer.win3.1x To set up Internet Explorer to use this news server, follow these steps: 1. In Internet Explorer, click the View menu, and then click Options. 2. On the Programs tab, click the News button. 3. In the News Server Address box, type: MSNEWS.MICROSOFT.COM Known Issues with Java on Windows 3.1 ------------------------------------- Java is a 32-bit multithreaded technology that uses case-sensitive long file names and UNICODE. Windows 3.1 does not provide these services, which means they have to be emulated in the virtual machine. Further, Windows 3.1 machines typically have slower processors and less memory than Windows 95 or Windows NT, so fewer resources are available to applications. As a result, it is not possible to provide the same Java experience on Windows 3.1 as on Windows 95 or Windows NT. Two of the symptoms you will see when you use Internet Explorer with Java applets are as follows: -- OutOfMemory exception on browser status bar. This message indicates an out-of-system-memory error. The Java virtual machine allocates limited memory for Java run time. If the Java applet is too big, it will use all the memory available on Windows 3.1. -- Random GPFs. This may happen when your system runs out of USER or GDI resources. The USER and GDI resources are limited on Windows 3.1 and they are shared by all programs. You may see GPFs occur in different applications when this happens. -- For non-Latin1 versions of Windows, this release of Internet Explorer does not support loading Java applets in directories named with extended characters. It will be supported in the next release. --------------------- KNOWN ISSUES AND BUGS --------------------- * No inline video. * No Internet shortcuts. * You cannot open another instance of Internet Explorer by double-clicking an .htm file in File Manager or double-clicking the Internet Explorer icon in Program Manager. To open a new instance of Internet Explorer, choose New Window from the File menu. * If you have voice messages waiting on your phone line (rapid beeps), our Dialer fails to dial out on the line. This can be remedied (for Hayes- compatible modems only) if, in the file Modems2.ini, at the end of the line for the InitString setting, you set "blind dialing" by typing: S6=5 * Internet Explorer might have difficulty loading a very large number of newsgroups (>16000). If your news server has a large number of newsgroups, you should use a dedicated newsreader to browse the groups. * After upgrading to version 3.02a, if you run an earlier version, you might get a dialog box stating "Could not :Load Entry Point in Security Protocol Module: Proxy_Basic=Proxy_basic_Load,basic.dll." Just click OK and continue or copy the Basic.dll from the 3.02a installation over the Basic.dll in the previous installation. * You might experience problems running some plug-ins. We are working with several vendors to resolve these issues. * If you are using an older phone system or hardware, or if you are installing a "generic" modem, the existing initialization settings for the modem might not be sufficient. If you have problems with the modem, you may need to modify the Modems2.ini file in order to change the initialization settings. Use Notepad or another text editor to open the file, and then, in the modems section, locate the line for the modem, and modify the INIT line as needed. * Pressing the TAB key does not select the Address bar as in previous versions. * If you are running Windows NT 3.51, the background of the Font Preview box (on the Font tab in the Internet Mail Options dialog box) will sometimes change colors. In some cases, this color may be very dark, making it impossible to see the font being previewed. It is, however, still possible to change the font. Restarting your computer a few times may solve the color problem.
