I didn’t want to create another VM to add on one version of software (why would I?), so I attempted to install version 26.03 on top of my other versions. I was running everything on a VMWare VM with Win10 Pro 64 bit installed.
The version of the software they were using at their plant was v26.03. I recently had to install a different version of Studio 5000 (formerly RSLogix5000 or just Logix5000) for a project for a customer. Use the Rockwell Product Compatibility Page to Avoid Frustration!
