[ABR-111646] A Hyper-V virtual machine cannot boot into 32-bit bootable media.
Solution: Use 64-bit bootable media.
[ABR-70817] If an entire machine is recovered with reboot and the recovery is initiated from some Linux distributions (for example, Ubuntu 15.10, Red Hat Enterprise Linux 7.2, and Debian 8.1), the operating system is unbootable.
Solution: Recover by using bootable media.
Centralized management

[ABR-111646] A Hyper-V virtual machine cannot boot into 32-bit bootable media.
Solution: Use 64-bit bootable media.
[ABR-70817] If an entire machine is recovered with reboot and the recovery is initiated from some Linux distributions (for example, Ubuntu 15.10, Red Hat Enterprise Linux 7.2, and Debian 8.1), the operating system is unbootable.
Solution: Recover by using bootable media.

Installation
[ABR-102251] Components for Remote installation are not installed if the Acronis Backup setup program is started from a network share.
Solution: Uninstall Components for Remote installation via Control Panel > Programs and Features; copy the setup program to a local folder; repeat the installation of Components for Remote installation.
[ABR-33952] Cannot remotely upgrade Acronis Backup & Recovery 11 Agent for Linux if the upgrade license is added to the license server but the full Acronis Backup & Recovery 11 license is not.
When installing Acronis Backup Management Server to Windows 10, where no Microsoft SQL Server instance is pre-installed, Acronis Backup setup would deploy Microsoft SQL Server 2008 Express. Although Microsoft SQL Server 2008 Express is not officially supported on Windows 10 by Microsoft, such setup was verified and no known issues were found. Workaround: before running Acronis Backup setup, install Microsoft SQL Server 2014 Express or any other edition on the target machine // use pre-installed Microsoft SQL Server 2014 on the target machine or on another machine on the network.
Local management

[ABR-111646] A Hyper-V virtual machine cannot boot into 32-bit bootable media.
Solution: Use 64-bit bootable media.
[ABR-70817] If an entire machine is recovered with reboot and the recovery is initiated from some Linux distributions (for example, Ubuntu 15.10, Red Hat Enterprise Linux 7.2, and Debian 8.1), the operating system is unbootable.

[ABR-33952] Cannot remotely upgrade Acronis Backup & Recovery 11 Agent for Linux if the upgrade license is added to the license server but the full Acronis Backup & Recovery 11 license is not.
When installing Acronis Backup Management Server to Windows 10, where no Microsoft SQL Server instance is pre-installed, Acronis Backup setup would deploy Microsoft SQL Server 2008 Express. Although Microsoft SQL Server 2008 Express is not officially supported on Windows 10 by Microsoft, such setup was verified and no known issues were found. Workaround: before running Acronis Backup setup, install Microsoft SQL Server 2014 Express or any other edition on the target machine // use pre-installed Microsoft SQL Server 2014 on the target machine or on another machine on the network.

[ABR-111646] A Hyper-V virtual machine cannot boot into 32-bit bootable media.
Solution: Use 64-bit bootable media.
[ABR-70817] If an entire machine is recovered with reboot and the recovery is initiated from some Linux distributions (for example, Ubuntu 15.10, Red Hat Enterprise Linux 7.2, and Debian 8.1), the operating system is unbootable.
