Hello,
I'm with the Support wing of LWD here, and I'd like to encourage you to try it out. I still see a handful of users with Windows XP Devices from time to time and I believe you should be fine to use Hero Lab on your older laptop.
I'd suggest cleaning up the computer by running a defrag, check for registry issues, and ensure you have all your hardware running the most recent versions of their respective drivers but I don't anticipate you having too much trouble.
If you run into any problems send me an email, and I'll see if I can help troubleshoot your situation.
Thanks!
