Reinstalling Watson Explorer

If you have previously installed an evaluation or beta version of Watson Explorer, you will eventually want to install an official release of Watson Explorer. Uninstalling Watson Explorer is discussed in Uninstalling Watson Explorer Modules. However, before re-installing Watson Explorer or related software modules using a locally-installed version of Installation Manager, you should make sure that no cached files from previous Watson Explorer installations are still located on your system. If cached files from previous Watson Explorer installations are still present on your system, version number collisions may cause out-dated files to be installed on your system.

To disable using (and retaining) cached files from previous versions of Watson Explorer:

• When using Installation Manager in graphical mode:
  1. Start the graphical version of Installation Manager and select File > Preferences
  2. Select Files for Rollback in the left pane
  3. Deselect the Save files for rollback checkbox
  4. Click Delete Saved Files
  5. Click Apply
  6. Click OK to close the Preferences dialog
• When using Installation Manager in command-line mode:
  1. Start the command-line version of Installation Manager, as discussed in Installing Watson Explorer from the Command-Line.
  2. Type P and press Enter to display the preferences screen
  3. Type 3 and press Enter to select the Files for rollback option
  4. Enter 1 to de-select the Save files for rollback option and press Enter
  5. If the Delete saved files option is listed, enter D to select that option and press Enter. (The Save files for rollback option is not listed if you do not currently have any saved files.)
  6. Type A to select the Apply Changes and Return to Preferences Menu option, and press Enter
  7. Type R and press Enter to return to the main Installation Manager screen.

Once you have configured Installation Manager so that it does not preserve these files, click Install on the main Installation Manager screen to being installing Watson Explorer and related software modules as discussed in:

• Graphical installation - See Installing Watson Explorer Graphically. The only difference between initialization as described in that topic and reinstallation is that you will not need to execute the launchpad.sh (Linux) or launchpad.bat (Windows) scripts, because Installation Manager is already installed.
• Command-Line installation - See Installing Watson Explorer from the Command-Line. The only difference between initialization as described in that topic and reinstallation is that you will not need to execute the launchpad-console.sh (Linux) or launchpad-console.bat (Windows) scripts, because Installation Manager is already installed.
