You may have trouble. Of course, you MIGHT be able to load her with out hair, clothes or other props on 64 MB, but even that isn't a given. I have 256 MB in my current set up, and once I add hair and a little clothing, it has already eaten up all the physical memory. I use a memory cleaner before launching, so I open Poser with about 210MB of physical memory free. If you have enough virtual memory, it's possible you could still work with her, but going to the hardrive for memory storage would really slow things to a crawl. She is definitely worth it, so it might be best to buy her before the sale ends and get the memory upgrade next. :-) One thing I am learning, however, is that the more memory the better. I'm adding another 256MB soon, but keep finding myself in a similar situation: "Do I buy memory this week, or order X item for poser". ;-)
