Then, registry entries like these indicate the application terminated abnormally at some point in the past:
Make sure there are no running sessions of our application. HKEY_CURRENT_USER\Software\JavaSoft\Prefs\com\ibm\/S/P/S/S\/Statistics\21.0ĭeleting this hive will reset the application back to its initial as-installed state with default user preferences.Ī working copy of user preferences will look something like this: Using IBM SPSS Statistics 21.0 as an example, they are here (for other versions of Statistics, replace all instances of '21' in the examples below with the two-digit version number of the product, such as '24'):
SPSS 16 TOOLBAR MISSING WINDOWS
On Windows platforms persistent user preferences can be viewed, exported, and imported using regedit. If they are corrupt they can not be restored. User defined toolbars will lost when you reset the defaults, but you can export and import them if you choose unless they are corrupt. The steps to restore defaults are made in the System Registry and therefore if you have a System Administrator, you may want to engage her to assist with these steps. On the Windows operating system, the problem is resolved by restoring the default toolbars as they were after the first install. This will reset the application back to its initial as-installed It is usually best to manually delete them from the Windows registry using regedit or some other tool.
Or if the user is running multiple sessions, there could be collisions while copying or writing the persisted user preferences, which could potentially corrupt them.Ĭorrupt user preferences are not easily repaired. Losing not only toolbar customization but also the default toolbars would indicate the user preferences have been corrupted. They will also be lost when the customization are created during a session that terminates abnormally. As such, toolbar customization can seemingly be 'lost' if the user is running multiple sessions simultaneously as illustrated in the scenario above. Toolbars are saved as part of user preferences. The working copy will not be written back to the persisted user User is maybe confused depending on expectations.Īlso, if a session crashes or is terminated abnormally (terminated using the Task Manager, for example) any changes to user preferences will be lost. User begins session C, which uses a copy of the user preferences written by session B. User ends session B, which overwrites the changes to user preferences written by session A. User ends session A, which writes its working copy to the persisted user preferences. User begins session B, which uses a copy of the same persisted user preferences copied by session A. User begins session A, which uses a copy of the persisted user preferences. Sequence of starting and stopping sessions becomes important. Knowing this, it is easy to imagine scenarios where the The working copy is used during the session and when the session ends, the working copy is written back to the persisted user preferences. This is done by making a working copy of the persisted user preferences when a session starts. Manage user preferences for each session separately so that changes to user preferences in one session do not affect other running sessions. In fact, this is necessary when running certain features such as the Production Facility. We allow users to run multiple sessions of the same version of our application simultaneously. Installers know nothing about user preferences. Even for the same Major.Minor version, installing and uninstalling will not add, remove or modify user preferences. Registered COM interfaces used for Scripting but these are not user preferences. Installing an additional version of our application will affect
There is no interaction of preferences between versions. Preferences for different Major.Minor versions of our application are stored separately. Java has APIs that manage user preferences and those are what we use. Regardless, we do not read or write directly to the Windows registry. On other platforms they are stored differently. On Windows platforms, Java stores user preferences in the Windows registry. IBM SPSS Statistics is a Java application and user preferences are stored as Java user preferences. To explain why this behavior can happen sometimes for some users we need to first explain how Statistics store user preferences.
