These issues affect installation on all platforms.
When the Installer is in the process of installing Message Queue 4.1 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 system has older versions of Message Queue and NSS/NSPR, the Installer's Upgrade only lists Message Queue needing upgrade; it does not mention that NSS/NSPR need to be upgraded. This only an issue with the Update screen as all the relevant software will be upgraded as part of the installation process (as indicated by The ReadyToInstall screen which shows the correct information). (Bug 6580696)
Workaround None needed as the NSS/NSPR files are installed if they are not current, and the older versions are unistalled.
When the Installer or Uninstaller is run in text mode (installer –t), the Summary screen shows the directory containing the log/summary files but does not list the names of these files. (Bug 6581592)
Specifying the name of a file that does not exist, produces inconsistent and unclear error messages. (Bug 6587127)
