WinZip(R) Self-Extractor 2.1 Copyright (C) 1995-1997 by Nico Mak Computing, Inc. All Rights Reserved Changes in version 2.1: * All 32-bit self-extracting Zip files support Microsoft(R) Authenticode(tm) technology. In earlier versions, the self-extracting Zip file's integrity check conflicted with Authenticode. (For information on Authenticode, visit the Microsoft home page, click the "Search" button and search for "authenticode code signing".) * User-specified icons: you can use an icon of your choice for all types of self-extractors except "Compact" and "MS-DOS + Windows". These icons are displayed in the Explorer (in version 2.0, user-specified icons were only used in the dialog box of self-extractors for software installation). * While version 2.0 make it possible to build 32-bit self-extracting Zip files, the program that created these 32-bit files was actually a 16-bit program. A 32-bit version (wzipse32.exe) is now included. * You can now create self-extracting Zip files that unzip automatically. (In version 2.0 the end-user had to specify /auto on the command line while running the self-extracting file to unzip automatically.) Use this new feature with caution: if you are planning to post this file on the Internet or an online service like CompuServe or AOL, you should be aware that some sysops refuse to accept files that unzip without a prompt. * The "Mail Self-Extracting Zip File: button in the final wizard panel makes it easy to send a self-extractor to another user by e-mail (this feature is available only if your system supports MAPI, the standard Mail Application Program Interface). * Password support for all types of self-extractors except "Compact" and "MS-DOS + Windows". Changes between release candidate 2 and release candidate 1 include: - Hourglass is now display consistantly during busy operations - WinZip Self-Extractor 2.1 now handles all zip files created on removable media by WinZip 6.3 beta versions. - Ampersands in user specified dialog text show up correctly. Changes between release candidate 1 and beta 5 include: - The -st switch now lets you specify the title bar text for "Standard 16-bit Windows" and "Standard 32-bit Windows 95 and NT" self-extracting files (in earlier versions the -st switch only worked for Self-Extractors for Software Installation). - Handle ".." as a directory name on the command line. - 32-bit self-extractors were not always changing to the correct directory before running the specified command after unzipping - Remove trailing any cr/lf characters from command strings in response files. - Fixes to out-of-memory errors in the the German language headers. Changes between beta 5 and beta 4 include: - 32-bit self-extractors are now compatibility with new Microsoft code-signing validation rules implemented in Internet Explorer 3.02. - Executable files are created with a lower case ".exe" extension under Windows 95 and NT (previous versions used an uppercase "EXE"). - A message warning that long names are truncated if a self-extractor is run on Windows 3.1 was sometimes not issued. Changes between version 2.1 beta 3 and 4 are minor. They include: - The warning that is normally displayed when creating a self-extracting zip file from a password protected zip is now not displayed when the -y command line option is used. - If you specify a dot (for "current working directory") as the "unzip to" folder while creating a self-extracting zip, the "Unzip To" field in the resulting self-extracting zip file contains the the name of the directory containing the self-extractor, so that users have a better idea of where the files will go. (This change was made to all types of self-extractors except the "Compact" Windows self-extractor.) - The "Mail" button was sometimes enabled when it shouldn't have been. - Improved wording of some error messages. Changes in version 2.0: WinZip Self-Extractor 2.0 is a superset of version 1.0. Everything that worked with version 1.0 works the same way with 2.0, but new features are available, including: * Options to create self-extracting ZIP files with new headers: * 32-bit Win32 headers * 16-bit Windows headers with Windows 95 long filename support * MS-DOS support (one EXE works on either MS-DOS or Windows) * Improved automation and customization for software installation, such as the ability to specify an icon and text for the main dialog box, and to delete temporary files after running a setup program. Includes support for Sterling Software's InstallShield SETUP program. * All versions can be created with English or German messages. * Ability to automatically extract files when EXE file is run. * An optional progress meter while unzipping. * An uninstall facility for the WinZip Self-Extractor package. * Command lines options can be included in a file using the @filename syntax, e.g. "winzipse @"continued_options.inp". * A Wizard to simplify the process of building self-extracting files.
