CorelDRAW Graphics Suite 12 on Windows 7 64 bit OS with RAM > 4 GB

I have bought a copy of CorelDRAW Graphics Suite 12 for Windows.  It goes without saying that it is a 32 bit program.

Then, I install it on my notebook computer with Windows Vista Business 64 bit OS with 4GB RAM.  I have tested each program of the suite.  Each of them works very well.

Then, I install another copy of CorelDRAW Graphics Suite 12 on a desktop computer running Windows 7 Ultimate 64 bit OS with 8GB RAM.

I then replace the kodakckms.dll with the newest version.  Every program of the suite turns out to be working well except that CorelDraw's memory option cannot go through.  It just shows 0 MB of RAM available and suggests me to exit and quit.

Does anybody have this experience?  Could you share your experience to solve this problem?

Thanks in advance.  [8-|]
