  2. In Windows Explorer, navigate to C:\Program Files (x86)\Bit9\Parity Server\hostpkg
  3. Obtain a copy of ParityHostAgent.Msi
  4. Distribute ParityHostAgent.Msi to a location that is accessible to the agents being upgraded.
  5. Login to the machine to be upgraded
  6. Open an admin CMD prompt 
  7. Run command:

Additional Notes

  • When the App Control Server is upgraded, a new version of "ParityHostAgent.msi" is created in the hostpkg directory. The newest version of the file should be used to ensure the agent is up to date.
  • If the installation fails, try disabling the tamper protection and setting the agent to allow uninstall from an Admin level cmd prompt:
cd c:\Program Files (x86)\Bit9\Parity Agent
dascli password <CliPasswordInsertedHere>
dascli tamperprotect 0
dascli allowuninstall 1
