In theory, RSView32 7.40 is compatible with Windows XP SP2.
But if you have a failed computer that is over ten years old, I would strongly recommend migrating your application to a modern operating system like Windows 7 Professional SP1 32-bit, and RSView32 7.60.
I sympathize; I am maintaining several old HMI systems, and have encountered challenges virtualizing and backing them up.
What is the exact error message ?
