WinZip(R) Install/Try Uninstall Component beta 8 Copyright (C) 1991-1996 Nico Mak Computing, Inc. All Rights Reserved #### PRE-RELEASE BETA TEST VERSION #### Be sure to read these notes before installing and using this software! This is the first pre-release beta version of the Install/Try/Uninstall component of WinZip that includes support for both Windows NT 4.0 and Windows 95. Previous 32-bit betas included support for Windows 95 only. This feature, also avialble in the release Windows 3.1 version of WinZip, lets you install, try, and UNINSTALL software distributed in ZIP files under Windows 95. Beta 8 adds support for Windows NT 4.0 Beta 7a fixes two bugs (beta 7 was intended to address these problems, but the distribution file accidentally contained the old beta 6 DLL): - A cosmetic flaw in the "View Configuration Changes" dialog box. In the rare situation where the "windows\nethood" folder does not exist, the text "Network Neighborhood" was displayed in front of new and modified files. - A rare "internal error" while building the display for the "View Configuration Changes" dialog box. There are no known bugs in this version - if you find problems, please report them by Internet email to support@winzip.com or post a message in the "WinZip Beta" section in the GO WINZIP area on CompuServe. Please do not post beta feedback in other forums or newsgroups, else they may never be seen by the developers. This feature REQUIRES WinZip 6.2, 6.1, or 6.0a; it will not work with the release version of WinZip 6.0. But if you are not using an earlier version, please download the free upgrade to WinZip 6.2. *** Caution *** This is pre-release software; use with caution. Be sure you have a good backup of your system files before running, just in case of problems *** Installation *** First install WinZip 6.2. Then copy the wzun95.dll and wz95.vxd files to your WinZip directory (usually c:\Program Files\WinZip). The next time you start WinZip the Install/Try/Uninstall feature will be operational (note that this feature only works on ZIP files containing a SETUP or INSTALL program). *** Feature Description *** WinZip's unique Install/Try/Uninstall feature makes it easy to install and uninstall software distributed in archives. This feature can save megabytes of disk space by tracking and removing all traces of an application. WinZip will run the installation program in an archive, give you a chance to try the program, and optionally offer to restore your system to its original state. The uninstall step can selectively remove files, icons, or program groups created by an install program, and can restore any altered INI files. You have complete control over the uninstall process, and no changes are made without approval. Note: the Install feature is only available if an archive contains an "install" or "setup" program. If the Install button is not displayed, use the CheckOut Feature to try the software in the archive. To use the Install/Try/Uninstall feature * Press the Install toolbar button or select Install from the Actions menu to extract all files to a temporary directory and run the install program. * Try the program that was installed. * Decide whether to leave the program installed or to uninstall. If you choose to uninstall, WinZip will display the Uninstall dialog box which will let you select whether to * Delete any Start Menu items created by the installation process. * Delete any Directories or files created by the installation process. * Restore your autoexec.bat, config.sys, registration database, or ini files if they were changed by the installation process. Restrictions: * All configuration changes made between an install and uninstall are considered to have been made by the install process. For example, if you switch to your word processor and save a document during the installation process, the document is considered to have been created as part of the install process. If you subsequently uninstall, WinZip will list the document you created in the Uninstall dialog box along with files created during the install procedure. Therefore it is strongly suggested that you do not run any programs other than those related to the program you are installing until you have decided whether to uninstall. * The uninstall procedure does not let you restore files that are changed or deleted unless they are one of the special files that are backed up during initialization: autoexec.bat, config.sys, and the .ini files in your Windows directory. Notes: * The uninstall feature does not attempt to save information across sessions. * The Install operation requires that the entire product being installed is distributed in one archive. * WinZip determines whether an archive contains an install or setup program by checking for a file that 1) is executable, 2) has "install" or "setup" in the filename, and 3) does not contain directory information. If no file matches these criteria the Install operation is disabled. * If the program you installed adds an uninstall routine to the Control Panel Add/Remove Programs applet, WinZip will offer to run the "Remove Program" feature. It will then give you a chance to uninstall any leftover changes to your system.
