There is no official 64-bit version of Omron Syswin 3.4. It is a discontinued legacy software originally released in 1999 for 16-bit and 32-bit systems like Windows 95, 98, and XP. Compatibility & Modern Systems
Because it was designed for older architecture, Syswin 3.4 typically does not run natively on Windows 10 or 11 (64-bit) without specialized setups. Virtual Machines:
The most reliable way to use Syswin 3.4 on a modern 64-bit PC is by running a virtual machine (such as VirtualBox ) with a guest operating system of Windows XP Windows 7 (32-bit) Compatibility Mode:
Some users have reported success by running the installer in "Windows XP (Service Pack 3)" compatibility mode, though this is often unstable for serial communication tasks. Licensing Issues: On newer systems, Syswin may only run in Demonstration Mode
, which prevents you from saving projects or going online with a PLC. Official Alternatives Omron has replaced Syswin with the software suite, which includes CX-Programmer Omron Automation Installing syswin 3.4 on win7 - PLCTalk.net
Omron SYSWIN 3.4 is a legacy 16-bit application originally released in 1999 for Windows 95 and Windows NT systems. Because it is a 16-bit program, it cannot run natively on any 64-bit version of Windows (such as Windows 7, 10, or 11 64-bit), as modern 64-bit operating systems lack the "NTVDM" (NT Virtual DOS Machine) required to execute 16-bit code. Solutions for 64-bit Systems
To access or work with SYSWIN projects on a modern 64-bit computer, you have two primary options:
Use CX-Programmer (Recommended): Modern Omron software like CX-Programmer (part of the CX-One suite) is fully compatible with 64-bit Windows. You can open original .swp project files directly in CX-Programmer by selecting "Syswin (*.swp)" in the "Files of type" dropdown during the open file dialog.
Virtual Machines: If you must use SYSWIN 3.4 itself, you need to set up a virtual machine (using software like VMware or VirtualBox) running a 32-bit version of Windows XP. Download and Availability
Official downloads for SYSWIN 3.4 are no longer hosted by Omron as it has been replaced by the Sysmac Studio and CX-One platforms.
Replacement Software: For current 64-bit support, register and download modern tools from the Omron Europe License Portal.
Manuals: You can still find the Syswin Operation Manual through official archive sites for reference on legacy PLC series like the CQM1 or C200H.
If you can replace the software instead of forcing compatibility, use CX-Programmer (part of Omron’s CX-One suite).
Migration tip: Syswin 3.4 files (.SWP or .CXT) can be imported into CX-Programmer (File → Import → Syswin project). Symbols and comments are preserved.
Why this is the best long-term solution:
Since a native 64-bit version does not exist, you must use one of the following methods to run Syswin 3.4 on modern hardware.
Yes. Syswin 3.4 fully supports C200H and C200HS. However, for C200HX/HG/HE, you may need CX-Programmer.
Omron officially discontinued SysWin decades ago, replacing it with CX-Programmer (part of the CX-One software suite) and subsequently CX-ONE and Sysmac Studio.
To summarize the technical reality:
If you are responsible for maintaining legacy Omron C-series PLCs, put effort into either a dedicated virtual machine or migrating to CX-One. The search for a mythical “Syswin 3.4 64-bit” will only waste time and risk your plant’s security.
For a safe, working download: Do not search for the software. Search for the method. Start by downloading VirtualBox and a Windows 7 32-bit ISO from approved sources. Then, contact Omron directly if you lack the original Syswin media.
