Keith, I ordered a custom made XP64 machine when XP64 was still in beta made. Amibroker 64 bit worked great with XP 64 beta. However, I went back to Amibroker 32 bit because TJ was too busy to also upgrade Amibroker 64 bit alongside the unbelievable progress that he has made improving the 32 bit version of Amibroker. To answer your program files question, Program Files (86) is for 32 bit programs, and PROGRAM FILES is for the 64 bit programs. I read very vew of these messages anymore, so I have no idea of when and if TJ will make Amibroker64 the same a Amibroker32. When and if he does, I will upgrade to the LATEST 64 bit version. Ron D

I just got my new system up and running with XP-64bit SP2, and want to install AB Pro 5.20, and use it to its full advantage. I also want to eventually use AB with IB. My XP-64bit has two folders for programs, "Program Files" and "Program Files (x86)". I guess that "Program Files" may be for 64bit programs, and "Program Files (x86)" for 32bit ones. Is that correct? Does it really matter? Which folder should I install AB in, or does it matter? What about IB TWS? Are there any other questions I should be asking before proceeding with the installation? Thanks for your help. -- Keith
