I have installed the latest version of the tool, 3.4, and installed it on an XP SP2 box. Everything looks good, but when I start it returns "C:\Program Files\Cisco Systems\Upgrade Tool\images\c1310-rcvk9w8-tar.124-10b.JA3 - LWAPP Recovery Image is not a valid one".
I have verified that the file exists and is named correctly. I have also downloaded a new copy of the application and image and installed on a different computer and got the same results. Any ideas?
