Hi,

Unfortunately, I don't. This is a special dev system I setup for 
a customer project. They have several 32bit only apps that force 
the 32bit requirement. Actually, I would be using D on 64bit 
anyway. I just happened to be working on this particular system 
when I decided to check out the latest D package. I will try the 
64bit package. In the mean time, I would be more than happy to 
gather any information that would help.

Thanks,
-G
