Atera can be installed using their deployment tool which uses RPC or via psexec using command prompt.

Note: Atera requires .net 3.5 to be installed prior to the agent install which can be problematic.

.Net Deployment:

PsExec.exe \\workstation_ip -u userid -p password -h DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

Agent Deployment

PsExec.exe \\workstation_ip -u userid -p password -h "\\CLIENT-DC\netlogon\AteraAgentSetup_Customized.exe" /InstallAgent

If you really want to get fancy, you can put those into Netscan 6.1.1 and you can use a hotkey to deploy to every computer on the network at once right within netscan. I found PSExec running within NetScan was a far better deployment method than Atera's deployment tool or their Login script as the login script also doesn't install .net prior to trying to install the agent.
