Manual or scheduled backups for a DC fails with the error:
"Failed to install the agent: %1 is not a valid Win32 application"
Confirm you can access the Admin$ share on the DC from the RMAD server using the same account the backup runs as:
\\DCName\Admin$
Try manually installing the agent on the DC.
If you can access the admin$ share and manually installing the agent does not work, please try rebooting the DC.
This can also be caused by firewall appliances between the RMAD server and the DCs.
Palo Alto malware protection has detected this as a threat before.
Check your firewall to make sure there is nothing interfering with this process.
