use Google Translate


Generally, you can uninstall Agents for Windows using Programs and Features of the Control panel.

Alternatively, you can uninstall agents using this script:

  1. Download the script and unpack it.
  2. Run the runme.bat script.
    Please note that uninstallation script uses PowerShell. Make sure that PowerShell execution policy is set for the user performing uninstallation.

Another way is to uninstall agents by running MsiExec.exe with the respective parameter:

  1. Open the Windows registry: Start -> Search -> regedit.exe
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products
  3. Search for "Acronis":
  4. Once found, go to the InstallProperties key and note the value of the UninstallString:

  5. Open the Command prompt: Start -> Search -> cmd.exe
  6. Type in the value you have noted from the UninstallString and add “/quiet” parameter:
    MsiExec.exe /X{GUID} /quiet

This command can be used to uninstall a particular build from any machine. The GUID changes when a new build of the agent is released and installed.
