- Common causes of failed file deletion include:
- The file is open in another window or process
- The file is locked
- You do not have permission to delete the file
Unzip the contents of the updates.zip archive that is now located your <APPIAN_HOME> directory.
Run the installJdk script (installJdk.bat on Windows, installJdk.sh on Linux).
If you maintain customized or overridden Spring Security .xml files, merge them with the associated base files in the /deployment/web.war/WEB-INF/conf/security/ directory.
Delete the following files:
