  1. Extract the install.jar to a temporary directory, for example: \temp\Extract
  2. Navigate to the extracted directory, and then browse to lib folder for example: \temp\Extract\tools\lib
  3. Remove the below files
    • log4j-1.2-api.jar
    • log4j-api.jar
    • log4j-core.jar
  4. Download the file attached to this knowledge document, log4j_1652279930171.jar , rename the file to log4j.jar and place under the extracted directory \temp\Extract\tools\lib
  5. Start the upgrade or install 


  • With upgrade to Clarity 16.0.2 its using Log4j version 2.17.2
  • If an install was successfully completed prior to completing these steps, no further action is required in order for Clarity to function. These steps are only required in order for the install.log to successfully update during the install or upgrade  process. This would be required if the install were failing, and the logs are needed to troubleshoot the issue, or if the install logs needed to be retained for some other specific purposes.
