Troubleshooting an Acronis "registration" error

Update 08/31/2026

This guide explains how to find a solution if the Acronis Agent for Swiss Backup asks you to register your machine and then returns an error when you click "Register Machine".

 

Manual registration…

In certain situations, particularly if you have (re)installed Acronis on your device, the application may ask you to register your machine and then display an error. In this case, you need to perform a manual Acronis registration according to your OS.

 

… on macOS

Refer to this other guide to uninstall the application.

Alternatively, run the following commands from a Terminal application (command-line interface, CLI) on your macOS device:

  1. To unregister, enter the following command:

    sudo "/Library/Application Support/BackupClient/Acronis/RegisterAgentTool/RegisterAgent" -o unregister -t cloud -a acronis.infomaniak.com
  2. To re-register, enter:

    sudo "/Library/Application Support/BackupClient/Acronis/RegisterAgentTool/RegisterAgent" -o register -t cloud -a acronis.infomaniak.com -u SBA-XXXX-XX -p "PASSWORD_HERE"
  3. Replace and complete the information specific to your account in the commands above, then enter your computer's password when prompted.

 

… on Windows

Use the Acronis cleanup tool to uninstall the application.

Alternatively, run the following commands from a Terminal application (command-line interface, CLI) on your Windows device:

  1. Open the Start menu by typing the following command:

    cmd
  • In the search results, right-click on cmd and select Run as administrator.
  • To unsubscribe, enter:

    cd "C:\Program Files\BackupClient\RegisterAgentTool\"
  • Then:

    .\register_agent.exe -o unregister -t cloud -a acronis.infomaniak.com
  • To re-register, enter:

    cd "C:\Program Files\BackupClient\RegisterAgentTool\"
  • Then:

    .\register_agent.exe -o register -t cloud -a acronis.infomaniak.com -u SBA-XXXX-XX -p "PASSWORD_HERE"
  • Replace and complete the information specific to your account in the commands above.

 

If you have Acronis 2FA enabled…

If Acronis two-factor authentication is enabled, the commands change slightly:

  1. Generate a registration token from https://acronis.infomaniak.com (need help?).
  2. Run the unregister command (see above, depending on your OS).
  3. Run the register command as described above, but adapt it as follows:
    1. … macOS

      sudo "/Library/Application Support/BackupClient/Acronis/RegisterAgentTool/RegisterAgent" -o register -t cloud -a acronis.infomaniak.com --token TOKEN_HERE
    2. … Windows

      .\register_agent.exe -o register -t cloud -a acronis.infomaniak.com --token TOKEN_HERE

 

Was the registration successful?

If you receive a 200 or "success" message, the command executed successfully.

If the result is different, take a screenshot of the error message and then contact Infomaniak support.
