  • Remote installation to Windows Server OS failed with the "The operation has failed with result '1603'" error
  • The server is a Domain Controller

The msi package installation log that can be found at C:\ProgramData\Acronis\InstallationLogs folder contains the following error:

Issue in the software. During installation the software tries to create the local service account to start Acronis Managed Machine Service and use it to install the service. 

The issue is planned to be fixed in future updates.


Run the installation file locally and install the agent: the setup program will prompt you to specify existing accounts (or the same account) for each service. There is no way to specify an existing account for Acronis Managed Machine service during the remote installation.
