Reinstalling Your Software
BEA Products Installation Guide 8-7
Notes: When you run the uninstallation program in silent mode, no messages are displayed
indicating the uninstallation is in progress or has completed successfully, even if errors
are encountered.
You can also include the
-log=full_path_to_log_file option in the command line
to create a verbose installation log. For example:
uninstall -mode=silent -log=C:\logs\weblogic_uninstall.log
For more information, see “Generating a Verbose Installation Log” on page 1-21.
Reinstalling Your Software
You cannot reinstall the same version of any BEA product on top of a previously installed version
of the same product—in the same BEA Home directory or in the same file location. You can,
however, add products and product components to an existing installation. For example, you can
install WebLogic Server during one installation, and Workshop for WebLogic Platform during a
separate installation.
To reinstall the same version of one of the product components or the entire BEA Products
distribution in the same location, you must first uninstall the previous installation.
If you try to install a complete copy of the BEA Products software in a BEA Home directory that
already contains a complete installation, an error message is displayed. Click or type
OK to return
to the Choose BEA Home directory prompt.
At the prompt, choose one of the following options:
z To continue installing the software using a different BEA Home directory, select an
existing BEA Home directory that does not contain a previous installation, or create a new
BEA Home directory.
z Exit the installation program. If you want to reinstall your BEA Products software in the
same BEA Home, you must uninstall the previous installation. You can invoke the
uninstall program appropriate for your platform, as described in one of the following
sections:
– “Uninstalling Your Software in Graphical Mode” on page 8-2
– “Uninstalling Your Software in Console Mode” on page 8-3
– “Uninstalling Your Software in Silent Mode” on page 8-5
Then reinstall the software as described in Chapter 2, “Starting the Installation Program.”
