These issues affect installation on all platforms.
The Ready to Install screen displays the product name as “mq” rather than as Sun Java System Message Queue 4.3. (Bug 6650841)
When the Installer is in the process of installing Message Queue 4.3 and the Progress screen is displayed, the Cancel button is active. Selecting the Cancel button at this time results in incomplete or broken installs. (Bug 6595578)
The Installer Summary Screen contains a number of links that when clicked will launch a log or summary page viewer. If you dismiss this viewer window using the window close button “X” instead of the button labelled “Close', you will not be able to bring this viewer window back up. (Bug 6587138)
Workaround: Use the button labeled Close to close the window.
When a computer system has older versions of Message Queue and NSS/NSPR, the installer's Upgrade screen only lists Message Queue as requiring upgrade; it does not mention that NSS and NSPR need to be upgraded as well. All the relevant software will nevertheless be upgraded (as indicated by The ReadyToInstall screen which shows the correct information). (Bug 6580696)
List of JDKs on JDK Selection Screen is active even when “Choose a JDK” option is not selected. (Bug 6650874)
When using the Message Queue uninstaller, clicking Cancel instead of Remove will still remove some installer files, and future uninstalls will fail. (Bug 6760416)
Running the installer in registration-only mode (installer -r) after performing a silent install in which registration was skipped, results in registration failing with "Premature end of file" error. (Bug 6767988)
When running the Message Queue 4.3 installer on a computer in which Open Message Queue has been previously installed, you might see the following warning message: "Error reading previous session data from Config-State." (Bug 6764305)
Workaround: The message is benign and will not recur once the install has been completed. Or you can remove the /var/install/config/mq/InstallDirectory.xcu file to avoid the message.
When running the Message Queue zip-based installer on a computer with no JDK installed, the following error message is displayed: "Invalid root in registry key "HKLM\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion." (Bug 6764358)
Workaround: Install the JDK prior to running the installer.
The mqInstallHome directory is created by the Message Queue installer even before you click the Install button on the Ready To Install screen. (Bug 6595590)
Trying to register Message Queue in text mode (installer -t -r) without having installed Message Queue throws a NullPtr Exception. (Bug 6760991)
Workaround: Install Message Queue before trying to register the installation.
