Why no XP-compatible version?

I downloaded the latest trial of Toon Boom Studio, and it won’t run on my laptop which is Windows XP. Is it possible to get older versions of the software? I just want to see if I like it enough to buy it, and if I do I’ll cross the new-laptop-bridge at that point.

Hi, There,
Toon Boom Studio could run in Windows XP system, please let me know more details about this issue, could you send me a screenshot ?

Windows XP is officially going away, and even Microsoft will no longer support XP come April 8, 2014. It makes no sense for software manufacturers to support obsolete and dead operating systems.
