Cause

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

Solution

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.

(!) This article applies to Build 27009 only. If the problem appears using another build/version of Acronis software then the following steps should be performed:

• collect fresh system report from the target server where the installation fails
• contact Acronis Support with a reference to this article
