As the title says, is there a package available for download anywhere, or maybe a firmware package stashed away on a hard drive somewhere?
It runs XP so I'd expect a standard installer, and it would be an easy upgrade if it were available, but while I've seen an application with several different version numbers, I have no idea which is the latest, and with the company buyouts and the many rebrands, I don't think I've yet checked all the places, but I'm out of ideas.
The most recent version I've seen is 2.60, but there could be more recent. It should work on 3251/3252/3252/3254 analyzers and any rebrands, so it may be worth uploading somewhere if someone's got access to it.
