Installation Monitoring Method
When using the
Installation Monitoring
method, the Repackaging Wizard monitors a system for any processes
that are created during an installation. The Installation Monitoring method determines the dynamic
interdependencies between files.
By monitoring these processes in the background, the Repackaging Wizard can identify files, shell links, and
registry entries that are added, modified, or removed by the installation. The resulting files and Repackager output
file can be converted into a Windows Installer package.
Installation Monitoring Method Considerations
Consider the following about Installation Monitoring when selecting a repackaging method:
•
Faster than Snapshot
—Installation Monitoring is significantly faster than the Snapshot repackaging method.
•
Clean system not required
—Although it is still a good practice to repackage on a clean system, it is not as
important when using Installation Monitoring technology as it is when you use the Snapshot method.
•
Can exclude processes from the project
—When using the Installation Monitoring method, you can
specify the processes that you want to exclude from the Installation Monitoring.
Snapshot Method
When using the
Snapshot
method, the Repackaging Wizard takes a reference snapshot of a system as a baseline
configuration, performs the installation, and then takes a second snapshot.
The difference between the two snapshots is stored in a directory you specify, along with the Repackager output
file (
.inc
). This file can then be converted into a Windows Installer package (
.msi
) using Repackager.
Snapshot Method Considerations
Consider the following about Snapshot technology when selecting a repackaging method:
•
Slower than Installation Monitoring
—The Snapshot method is significantly slower than the Installation
Monitoring repackaging method.
•
Clean system is required
—When repackaging using Snapshot technology, you should use a clean system,
with a baseline configuration for your target environment. If you do not repackage on a clean system, you may
not capture all of the necessary files for the setup because the files may already be installed on the system.
•
Exclude anti-virus software directories
—Any machine that you use to repackage most likely has anti-
virus software installed on it, even a “clean” machine. While you are repackaging an application, the real-time
virus detection feature of anti-virus software could automatically update various cached files in its directories.
In order to avoid repackaging errors when using the
Snapshot
method, you should exclude these directories.
See
Excluding Directories and Subdirectories
for more information.
Note •
Anti-virus software does not affect repackaging using the
Installation Monitoring
method.
