To avoid duplicate entries in the Windows Control Panel and incorrect plug-in version numbers in your IDEs, uninstall the current version of Klocwork before downgrading to a previous version.

Before you uninstall

If you will be modifying or uninstalling a Server package or connected desktop installation, you must stop the Klocwork Servers first. See Stopping the Klocwork Servers.

If you are uninstalling the Server package, in addition to stopping the servers, you should also make a backup copy of your projects_root directory and any configuration files you modified, such as kwfilter.conf). For Unix and Windows, compiler configuration files are located in <server_install>/config; for Mac they are located at /Library/Frameworks/KlocworkServer.framework/<version>/config. For more information about backing up data, see Backing up Klocwork data.

While the Windows version of the Klocwork Server package won't uninstall the projects_root directory or configuration files, it's a good idea to make a backup of these directories. For Unix systems, there is no automated uninstall, so make sure you back up your projects_root and any other data files you want to keep and store them outside your Server installation directory. Then you can delete the Server installation directory.
