When installing Windows Agent 8.10.0 using the latest Policy Installer the Configlist is not included at the time of install
This issue was tracked under EPCB-23124 and resolved with the release of Agent 8.10.2.
Upgrading the Agent Installer to 8.10.2 will prevent the issue. In the meantime, there are potential workarounds for Agent install:
"C:\Program Files (x86)\Bit9\Parity Agent\dascli.exe" stopservice
\Bit9\Parity Server\configxml\configlist.mxlC:\ProgramData\Bit9\Parity Agent\configlistfull.bt9net start parity
