You have a Windows Server 2003 with Microsoft SQL. You have Agent for Windows installed on the machine.

You would like to install Agent for SQL to make incremental backups of SQL Databases, but the installation fails with:

Windows cannot open this program because it has been prevented by software restriction policy.

Although the installation is run by administrator, and the software restriction policies are disabled or are not blocking Acronis installer.


Installation requires all the modules to be installed at the same time.


  1. Uninstall Agent for Windows. During uninstallation, do not select 'Remove the logs and configuration settings'.
  2. Re-install it again using the same credentials, same service user but this time add Agent for SQL to the 'What to install' list.
