Some folks have reported issues with the version of SetupEOSInfo.exe that I put up the other day. Let's try again, shall we? I'm using another different packager, I think this will do the trick. As always, let me know if you have issues.
Also, I've updated EOSInfo to version 0.2 - it'll now accept changes for the Owner, Artist, and Copyright fields (if your camera model supports them, of course). I think I may have fixed the issue with serial numbers on cameras after the 40D, as well.
