62569: Acronis Cyber Protect, Acronis Cyber Backup: device does not appear in backup management console after installation

Last update: 31-05-2021


You have installed Acronis Agent and registered it in your account, but when you open the backup management console, this device is not listed in Devices.

In mms log on the affected machine (located in C:\ProgramData\Acronis\BackupAndRecovery\MMS\), you see this error:

| error 0x1403f4: WMI 'ExecQuery' failed for query '%ls'.
| line: 0xc523d9a02d03d55c
| file: e:\310\core\winex\wmi_acc.cpp:305
| function: Windows::WMIClass::Select
| Query: SELECT * FROM Win32_OperatingSystem
| $module: mms_vs_12420


WMI is Windows Management Instrumentation, Acronis uses its functionality on Windows machines to get information about disks, system and services.

The error indicates that Acronis Agent had attempted a query via WMI tools and WMI tools failed to process it.

This is often caused by WMI repository issues in the Windows OS.


Issues with WMI must be fixed in order for Acronis products to work. We recommend contacting Microsoft support for assistance with WMI errors.
