If you are trying to get RSLogix 500 CPR9 to recognize a verified master disk and are hitting a wall, use this structural troubleshooting path: Step 1: Verify the EVRSI Environment Variable
To transfer the license to another computer:
Follow the on-screen prompts to install the CPR9 shared components and FactoryTalk services.
Run the EvMove utility completely inside the isolated guest environment to avoid modern Windows security restrictions. Compatibility Mode Adjustments If installing directly onto a host Windows 10 machine: Right-click the RSLogix 500 shortcut and select . Navigate to the Compatibility tab. rslogix 500 81000 cpr9 w master disk verified
| Term | Meaning | Significance | | :--- | :--- | :--- | | | The software itself. The programming environment for SLC 500 and MicroLogix PLCs. | The core tool for creating, editing, and troubleshooting programs for these controllers. | | 8.10.00 | The software's specific version number. | This is a "point release" that provides a snapshot of the software's features and hardware support at a given time. | | CPR 9 | Stands for "Coordinated Product Release 9". | A major Rockwell initiative to synchronize the release of its entire software suite (including RSLogix, FactoryTalk, RSLinx) for seamless interoperability. | | "w Master Disk Verified" | A licensing and activation phrase. | Indicates the software uses a physical "Master Disk" (typically a 3.5-inch floppy) containing a critical activation file. "Verified" likely means the disk is original and functional, not a copy. |
A "verified" installation ensures that you have full access to online monitoring, editing, and saving capabilities. Without verification, RSLogix 500 may run in "Lite" or "Demo" mode, which restricts your ability to communicate with the PLC—a critical failure point during a factory breakdown. Best Practices for Modern Users
The native and most stable environment for this software version. EVRSI activations run flawlessly here because the operating system permits direct low-level access to the root directory for the EVRSI.SYS folder. If you are trying to get RSLogix 500
| Term | Explanation | |------|-------------| | | The standard IEC‑1131‑compliant ladder‑logic programming environment for SLC 500 and MicroLogix processors. | | 81000 | Likely a catalog number or internal part number for this software package or a specific order code. | | CPR 9 | A Rockwell internal version‑tracking label that ensures all product components (RSLogix, RSLinx, FactoryTalk Services) are compatible with each other. | | W Master Disk Verified | Indicates that the original “Master Disk” (typically a 3.5‑inch floppy disk) has been checked and is known to contain a valid software activation. |
Legacy EVMOVE activations write hidden system files directly to the root directory ( C:\ ). Modern versions of Windows strictly block root-level modifications for security reasons.
When working with legacy master disks, you are likely to encounter a few standard errors. Here is how to resolve them: "Activation Not Found - Running in Demo Mode" Navigate to the Compatibility tab
The Master Disk must have its physical write-protect tab closed during use, as the utility needs to write back to the disk to register that the license has been removed. 3. How to Verify a "Master Disk Verified" Status
