Sculptris Crashing in Win 7

[kenw]

I'm using a dual core, 3GHz, 8Gig ram, 64 bit Win 7 pc. In theory this should run Sculptris, but when I start working in Sculptris it keeps crashing.

I can open the program, and get the sphere and change it to a plane if I want. But as soon as I start using tools for modelling, it crashes. The only tool that works properly is Inflate, Pinch will not work at all.

Any ideas what's happening here please?

New computer? Probably need to update or "backdate" your graphics drivers. Probably came with DirectX11 installed, which is supposed to take care of DirectX9 stuff ... but I had to install DirectX9c as well to get it to work ....

My pc is about a year old, strange thing is a recent attempt to upgrade the drivers on the graphics card failed. Although this problem predates that. I'll download DirectX 9c, and try it out. Thanks for that tip.

I have a similar problem. Allow me to elaborate and pose a possible cause for this issue in this specific instance.
My system consists of the following:
-AMD FX-4100 Quad-Core Processor 3.6 GHz
-8GB (2 x 4GB) G.Skill Sniper RAM
-NVidia GeForce GTX 560 Ti GPU (1GB memory)
-Seagate SATA 2TB HDD
-Seagate SATA 320GB HDD
-Wacom Intuos 3 tablet

When I run Sculptris, it seems to work fine, but the moment I apply any tool to the model, my processor(s) shoot(s) to 100% usage and holds there until either I release my pen from my tablet or the program crashes. When it crashes, it usually just disappears and provides no error message or error code and my system runs as usual otherwise.
It seems there is a driver issue of some sort that's causing the program to lock up or run into an endless loop scenario when tools are applied to the model. The model is edited as usual, but the program lags badly after a little while and will crash every time. When the processor(s) max out, it goes to 100% on all four cores and stays there. Never comes down below 100%, not even to 99% for even a moment until I stop editing the model.

I have not found a solution as of yet.
