Version 8.10 is unique because it supports two distinct licensing methods:
EVRSI (Master Disk): This legacy system uses a physical 3.5" floppy disk to "move" a license onto a computer's hard drive. The software checks for hidden activation files in the root directory before allowing online/offline programming.
FactoryTalk Activation: This was the new, internet-based system introduced with CPR 9. Starting with v8.10, a valid serial number became mandatory during installation to facilitate the transition to this newer licensing model. Summary of Key Features (v8.10) Feature Category New Hardware MicroLogix 1400 Series A , SLC 5/0x FRN-11 Messaging
Modbus RTU Master support, SMTP (email) support (except on Vista) Security Added FactoryTalk Security LogOn/LogOff capabilities Legacy End-of-Life Last release to support the older EVRSI activation method
For those looking to troubleshoot or manage these legacy licenses, the EVMOVE.EXE or RESETW.EXE utilities found on the Master Disk are essential for moving activations between machines.

RSLogix 500 Version 8.10.00 (part of Coordinated Product Release 9, or CPR9) represents a significant milestone in Rockwell Automation’s software lifecycle. Released around June 2008, it serves as a critical bridge between legacy floppy-disk-based activation and the modern FactoryTalk digital licensing ecosystem. The Role of Version 8.10 (CPR9)
CPR9 is a "Coordinated Product Release," a designation used by Rockwell to ensure that different software packages (like RSLogix 500, RSLinx, and FactoryTalk View) are tested for seamless interoperability. Version 8.10 was the first to introduce broad support for then-new hardware like the MicroLogix 1400 and newer firmware for SLC 5/03, 5/04, and 5/05 processors. The "Master Disk" and EVRSI Activation

RSLogix 500 version 8.10.00 (CPR9) is a significant legacy release for Allen-Bradley PLC programming. It is notably the final version to support the original Master Disk (EVRSI) activation method before Rockwell Automation transitioned fully to FactoryTalk Activation. Key Features of Version 8.10
Expanded Hardware Support: This version introduced compatibility for the MicroLogix 1400 controller and updated firmware (FRN 11) for modular SLC controllers.
Operating System Compatibility: It was designed for use on older systems including Windows Vista (32-bit), Windows XP (SP2), and Windows Server 2003. It is generally not compatible with modern systems like Windows 11 without virtualization.
Instruction Set: Includes standard ladder logic instructions such as Read Program Checksum (RPC) and messaging instructions (CEM, DEM, EEM) for ControlNet and EtherNet. Activation & Master Disk Details

The Automation Veteran
John had spent over two decades working in industrial automation. He had seen it all - from dusty old PLCs to state-of-the-art robotic arms. But despite the changing landscape, one thing remained constant: his trusty RSLogix 500 software.
As a young engineer, John had cut his teeth on RSLogix 500, learning the ins and outs of ladder logic and PLC programming. Over the years, he had worked on countless projects, from simple motor control systems to complex process automation applications.
One day, John received a call from an old client, asking him to revisit a project from years ago. The client's manufacturing line was still humming along, but they needed to upgrade their PLC to handle some new requirements. John agreed to take on the challenge.
As he arrived on site, John was greeted by a familiar sight: an 81000 series PLC, still chugging along after all these years. He smiled, remembering the countless hours he had spent programming and troubleshooting these units. The client handed him a CD with the latest RSLogix 500 software: CPR9, with a Master Disk.
John popped the CD into his laptop and began to work his magic. He loaded the new software, and began to review the existing code. As he worked, he noticed that the client's system was still running on an older version of the software. He knew that updating to CPR9 would not only bring the system up to date, but also provide some much-needed security patches and features.
With the Master Disk, John was able to easily configure the PLC and get the system up and running quickly. He spent the next few days testing and validating the new code, making sure everything was working smoothly.
As the project neared completion, John took a moment to reflect on his career. He had seen a lot of changes in the industry, but one thing remained constant: the importance of reliable, efficient automation systems. And RSLogix 500, with its powerful features and flexibility, had been a trusted companion throughout his journey.
The client was thrilled with the upgrade, and John felt a sense of satisfaction knowing that his work would keep their manufacturing line running smoothly for years to come. As he packed up his tools and headed home, John couldn't help but feel a sense of pride and nostalgia. He had come a long way since his early days as a young engineer, but RSLogix 500 had been there every step of the way.
The End
The phrase RSLogix 500 8.10.00 CPR9 with Master Disk refers to a specific, legacy configuration of Rockwell Automation’s ladder logic programming software. While modern automation has shifted toward Studio 5000 and the Logix 5000 family, RSLogix 500 remains the backbone for maintaining SLC 500 and MicroLogix controllers. Understanding the Technical Terms
To navigate this specific version, it helps to break down what these identifiers actually mean:
Version 8.10.00: This version was a pivotal update that improved compatibility with Windows XP and Windows 7. It allows for the configuration of modern I/O modules and provides the instruction set necessary for complex math and data handling.
CPR9 (Coordinated Product Release 9): This is Rockwell’s way of ensuring that different software packages (like RSLogix, RSLinx Classic, and FactoryTalk View) work together on the same operating system version without conflicts.
Master Disk: In the "classic" era of industrial software, the Master Disk was a physical floppy disk or a digital "key" file used for software activation. It preceded the modern FactoryTalk Activation Manager system. The Role of the Master Disk Today Subject: [SOLVED] Understanding RSLogix 500 Error 81000 and
For many engineers working on older factory floors, the "Master Disk" represents the EVMOVE or Move activation method. Modern computers no longer have floppy drives, which creates a hurdle for legacy systems.
If you are trying to activate RSLogix 500 v8.10 today, you generally have two paths:
Legacy Transfer: Using a USB floppy drive to transfer the "Master" key to the hard drive via the EVMOVE.EXE utility.
Activation Migration: Converting the old master disk serial number into a modern Product Key and Serial Number to be used with FactoryTalk Activation Manager. Compatibility and Virtualization
Because RSLogix 500 v8.10.00 was designed during the Windows XP/7 era, running it on Windows 10 or 11 can be tricky. Most professionals use Virtual Machines (VMs) to host a stable environment for these legacy tools. This prevents the "Master Disk" activation from being corrupted by modern OS updates. Why Stick with 8.10.00?
While higher versions exist (up to v12+), v8.10.00 is often the "goldilocks" version for older plants. It is stable, supports almost every MicroLogix and SLC processor ever made, and doesn't require the heavy system resources of the newest releases.
If you're troubleshooting a faulted PLC or performing a program backup, having this specific version—and the means to activate it—is essential for avoiding downtime.

Body:
I recently ran into a frustrating issue while trying to migrate an old SLC 500 project to a new laptop, and I wanted to share the resolution to save others the headache. If you are seeing "Error 81000" in RSLogix 500 and your software is demanding a "Master Disk," here is the breakdown of what is happening and how to fix it.
If you have the physical disk or an ISO and you are encountering errors, here is the fix list.
Error: "Missing Master Disk"
Error: "EVRSI Device Driver Not Loaded"
Error: "Invalid Disk"
Error: "This is a CPR 7 disk"

If you inherit a plant floor PC running RSLogix 500 CPR9, and the hard drive crashes, you cannot simply download the software from Rockwell’s website unless you have a current support contract (which is expensive for legacy software). However, if you have the original master disk, you can rebuild that PC completely offline.
