The certificates that are used to sign Acronis Remote Installation files are not installed on the target server. 


In order to fix the problem the missing certificates should be installed on the target server:

  • Download attached archive certificates.zip that contains two root certificates 
  • Unzip the archive
  • install the certificates on the target server: right click on .cer file and choose the option to install the certificate

After the certificates are installed the remote installation procedure can be started again.

Alternatively, you can install Agent locally, as the certificates are not checked during local installation. See Installing Agents Locally for instructions.
