Cause
- VMware Carbon Black App Control Agent has Tamper Protection enabled.
- The VMWare Carbon Black App Control Agent is still running on the sensor during the EDR install/upgrade.
Resolution
- To disable Tamper Protection, please see this KB for reference: Disabling Tamper Protection
- On later App Control versions, the local service (parity agent) also needs to be stopped/disabled: Disable Parity Agent Via CLI
- This has been fixed in the 8.x App Control agent version, thus this step can be avoided by upgrading to a more recent version.
