Smartpatch - Symantec WISESCRIPT PACKAGE EDITOR 7.0 SP2 - FOR WISE INSTALLATION STUDIO V1.0 Installation Manual

SmartPatch

WiseScript Package Editor Reference
WiseScript Package Editor only
Use the SmartPatch™ page to turn an installation into an upgrade (patch), instead of a
full version installation. When you distribute installations of this type, the destination
computer must contain a previous version of the application for the installation to be
successful.
To create a smart patch, make sure your computer contains a copy of the old software
that is being upgraded. After you specify the path to the old software, the SmartPatch
feature compares the older versions of the application to the version being installed and
generates a patch installation that contains only the differences between the two
versions. This can result in a significantly smaller installation file. If you specify multiple
previous versions, they're upgraded no matter what version is on the destination
computer.
Select Installation Expert > SmartPatch page and complete the page:
Do Not Create SmartPatch Updates
Mark this to create a full installation and not use the SmartPatch feature. You can
also leave this feature off while testing an installation, to produce faster compiles.
Create SmartPatch Updates
Mark this to enable SmartPatch and the following fields:
Error Checking
By default, SmartPatch expects the same file names to exist in both the old and
new copies of the software and displays errors when they don't match. You can
change the default level of error checking.
Do not display errors
Select this option if you expect a significantly different file set in the new
installation.
Display error if all matching files not found
Select this option to prevent errors such as specifying an empty or incorrect
directory for the old software.
Display error if any matching files not found
Select this option if the old and new installations should have all the same
file names, but different versions.
Patch Threshold
Determines at what point SmartPatch simply includes the entire new file rather
than creating a patch. The default is 85%, meaning that when the patch file (for
all versions to be updated by SmartPatch) is at least 85% of the size of the
complete file, the complete file is included rather than the patch. However, even
though the entire file is included in the installation, it is not installed unless the
end user has a valid copy of an older version of the file.
Maximum Memory
Determines how much memory the SmartPatch feature can use. SmartPatch is
very memory-intensive. Set this value to 2 MB less than the amount of RAM
installed in your computer.
