Be sure to read the notes below before installing and using this software!
This feature requires the 32-bit version of
(version 6.2 or 6.3).
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.
First install the 32-bit version of WinZip. Then download and run
wzun32b8.exe, the Install/Try/Uninstall distribution file. 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).
WinZip's unique Install/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/Uninstall feature
If you choose to uninstall, WinZip will display the Uninstall dialog box
which will let you select whether to
- Press the Install toolbar button or select Install from the Actions
menu to extract all files to a temporary directory and run the
- Try the program that was installed.
- Decide whether to leave the program installed or to uninstall.
- 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.
- 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.
- The uninstall feature does not notice files or directories created
from DOS boxes (after all, this is a Windows program!).
- The uninstall feature does not attempt to save information across
- 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.
