Download and install SymplyATOM2 on Windows using the combined Setup installer, which automatically installs all required drivers and tools in a single pass.

TABLE OF CONTENTS

Overview

The SymplyATOM2 Windows installer is a single .exe file that installs everything SymplyATOM2 needs in one pass. You do not need to download or install any drivers or tools separately. The following components are installed automatically, only if not already present on your system:

ComponentPurposeRestart required
Visual C++ 2015–2022 RuntimeRequired by SymplyATOM2 and associated toolsNo
ATTO360 Storage Suite & ExpressSAS driverHBA driver that gives Windows access to the connected LTO tape driveYes
IBM Tape Diagnostic Tool (ITDT)Low-level tape drive diagnostics engine used by SymplyATOM2No
IBM LTFS SDELinear Tape File System driver, required for LTFS tape operationsYes
SymplyATOM2The SymplyATOM2 applicationNo

A Windows restart is recommended after installation. The ATTO ExpressSAS and IBM LTFS drivers both require a restart before they become fully active. SymplyATOM2 will launch immediately after the installer finishes, but your tape drive will not be detected until Windows has been restarted.

Signed and trustedAs of build 2.0.2.30, the SymplyATOM2 installer and the installed application are digitally signed with a Microsoft Trusted Signing certificate. Windows will recognise SymplyATOM2 as coming from a verified publisher, so you should not see a SmartScreen or “unrecognised publisher” warning when you run it.

Step 3 - Allow the UAC prompt

Windows will display a User Account Control prompt asking “Do you want to allow this app to make changes to your device?” The installer requires administrator privileges to install drivers and system components. Because the installer is signed, the prompt will show it coming from a verified publisher rather than “Unknown”.

1
Click Yes in the UAC prompt. If you are logged in as a standard user, you will be asked to enter an administrator password before proceeding.

1
Click OK to dismiss the dialog. Save any open work in other applications, then restart your PC.
Restart required before tape drives are detectedThe ATTO ExpressSAS driver and IBM LTFS must complete loading during a full Windows restart before SymplyATOM2 can detect your tape drive. If you skip the restart, the Drives panel will remain empty.

Step 6 - Verify and launch

1
After restarting, open SymplyATOM2 from the Start Menu or your Desktop shortcut. If your ATTO ExpressSAS HBA and LTO tape drive are connected and powered on, the drive will appear in the Drives panel on the left.

Frequently asked questions

Will Windows show a security warning when I run the installer?

No. As of build 2.0.2.30, both the SymplyATOM2 installer and the installed application are digitally signed with a Microsoft Trusted Signing certificate. Windows Defender SmartScreen and the UAC elevation prompt will recognise SymplyATOM2 as coming from a verified publisher, so you should not see a security warning or an “Unknown publisher” prompt. If you see one anyway, you may be running an older installer downloaded before this build - re-download the current version from the SymplyATOM2 Release & Download article and try again.

Do I need to install any drivers or tools separately?

No. The SymplyATOM2 Setup installer includes everything required: the VC++ runtime, ATTO360 Storage Suite and ExpressSAS driver, IBM ITDT, and IBM LTFS. Each component is only installed if it is not already present, so running the installer on a machine that already has some components will not reinstall or downgrade them.

My tape drive does not appear in SymplyATOM2 after installation

Check the following in order:

  • Confirm that Windows has been fully restarted after installation. The ATTO ExpressSAS driver does not become active until after a restart.
  • Verify that the ATTO ExpressSAS HBA is correctly seated and that the tape drive is powered on before launching SymplyATOM2.
  • Open Device Manager (right-click the Start button › Device Manager) and look for the ATTO ExpressSAS adapter under Storage controllers. If it shows a warning icon, the driver may not have installed correctly - try running the Setup installer again.
  • Check that the tape drive is visible in Device Manager under Tape drives. If it is absent, the issue is with the HBA or cabling rather than the software.

If the drive still does not appear after checking all of the above, submit a support ticket.

What version of Windows is required?

SymplyATOM2 requires Windows 10 version 1809 (October 2018 Update) or later, 64-bit. 32-bit Windows is not supported. The installer will refuse to run on unsupported versions.

Can I run SymplyATOM2 without restarting after installation?

SymplyATOM2 will launch and open immediately after installation without a restart. However, the ATTO ExpressSAS driver and IBM LTFS filesystem driver both require a Windows restart to become fully active. Until you restart, the Drives panel will remain empty and no tape drive operations will be available.

Will the drivers survive a Windows update?

Yes. Standard Windows updates do not remove or disable third-party drivers installed via their own installers. Major Windows feature updates (e.g. upgrading from Windows 10 to Windows 11) may prompt a driver compatibility check but will not remove installed components. If a Windows update causes the tape drive to stop appearing, run the SymplyATOM2 Setup installer again to repair or reinstall the affected components.
