Preinstallation Tasks
This topic describes tasks to perform before installation.
-
Log in to Windows as an administrator, as you must have
administrator privileges to run the installer and install some
components. -
Read the release bulletins for the latest information on the
products that you are installing. Release bulletin is available on the
Appeon website at https://docs.appeon.com/pb/release_bulletin_for_pb/index.html. -
Make sure the drive on which you install PowerBuilder is not
compressed. If compression is enabled on the installation drive, the
installer fails. -
Make sure you have a TEMP environment variable that points to an
existing directory location with at least 2GB free space. The
installer writes files to this directory during the installation and
frees the space after the installation is complete. -
Close any open applications.
-
Back up any files created with earlier versions of Appeon
products. Make sure that any PBLs you plan to upgrade have been
regenerated without error in your current version of PowerBuilder
before you back them up.In addition to backing up your PBLs, back up any files that
contain information you do not want to lose, such as database files,
INI files, preference information, and modified database definition
files. For more information about backing up and upgrading existing
applications, see Postinstallation Tasks. -
Read the section called “Software Requirements” to determine
whether you need to install any software before installing
PowerBuilder.
