Is it possible to make Rhino4.0 to use up to 4GB on Windows 7 64bit professional?

Hi,

I have to work with Rhino 4.0 these days but I often encounter "out of memory" problem when Rhino use up 2GB memory because 2GB seems to be the default maximum for a 32bit software running on a 64bit win7 system.

I searched and found this article http://msdn.microsoft.com/en-us/library/windows/desktop/bb613473%28...

It' s about the 4G tuning and said to set the IMAGE_FILE_LARGE_ADDRESS_AWARE flag in the image header to make 32bit software use up to 4GB memory.

I also found a little tool, http://www.ntcore.com/4gb_patch.php

This is used to add that flag I suppose. I tried it on rhino 4.0 but still, it crashed when it consumes 2GB memory.

My question is, is it possible to make Rhino4.0 to use up to 4GB on Windows 7 64bit system? If the answer is yes, and how?

Thanks!
