Up to now, I had not become aware of the 32-bits restriction on the home editions, since I am still working with a 32-bits machine and never paid special attention to that. However, I am now thinking of buying an Intel Core i7 (64 bits) windows 7 based machine, mainly to run my (personal) heavy Mathematica stuff (computation and graphics developed on both, V6.01 full international license and v7.01 Home Edition, -- the V7 home to be upgraded to V8 home if finally I have the answers to questions I made to the WRI customer service at the beginning of January after having unsuccessfully attempted to try the V8-Trial). Now, I am at a loss, since, for example, my V6.0.1 (in the "About Wolfram Mathematica", also appears: "Plattform 32-bits"). So, I have this question to the very experts in the group. Does this restriction mean that the Mathematica home editions would not work at all on 64 bits machines or just that it/they would not take adventage of the whole power of the 64 bits multiple nucleus architectures? I assume that the full V6.0.1 licensed will run freely on 64-bits. So, If the home editions (V7/V8) still work on a 64-bits machine, though restricted to 32-bits, in which way, if any, would the 32-based editions would use the four nucleus of the Intel Core i7/i5 (64 bits)? Will it depend either on the way Mathematica uses the procesors that or on the way Windows emulates 32 bits applications? E. Martin-Serrano P.S. Just for it is of any use to anyone. It seems that the download files (in general, but specially the huge 922Mb V8-Trial file) are vulnerable to the downloading process. After taking all kind of precautions to not interfere with the transfer, I have tried to download at least six times the V8 installation file over an ADSL 6-Mb line, and all of downloaded files came corrupted. Maybe the line had problems,... maybe, but the SPI (Telefonica) denied that fact after my complains. As a result,I gave up to check the trial on January 6 or so, and ask the customer service about the issue. But, beware, the fact to take in a account is that I have had problems with corrupted files in downloading other different WRI application files before (V7.01, WorkBench 1, and WorkBench 2) and finally, en each and every case, WRI solved the problem by sending me a direct link to a different named file (containing the same application) which I downloaded at the first attempt whithout any problem at all. This suggests me that the trouble would be in the file itself and not in the line. -----Original Message----- From: David Kirkby [mailto:drkirkby at gmail.com] Sent: Friday, February 04, 2011 7:42 AM To: mathgroup at smc.vnet.net Subject: [mg116216] [mg116190] Re: Mathematica 8 Home Edition On Feb 2, 11:07 am, Daniel Lichtblau <d... at wolfram.com> wrote: > AES wrote: > > In article <ii5rii$fi... at smc.vnet.net>, > > Murray Eisenberg <mur... at math.umass.edu> wrote: > > >> So far as I am aware, for a given version number, e.g., 8.0.0, the > >> regular (i.e., "Professional") edition = Home Edition = Student Edition > >> with respect to features. > > >> The two aspects that _may_ differ are: (1) kind of support provided by > >> Wolfram Research (beyond installation issues), and (2) whether some > >> special identification of the edition appears on printed pages. > > > And, the legal restrictions that you (purportedly!) agree to, and even > > commit others to, when you purchase and use the Home Edition. > > > Last time I looked at the fine print of these was several years ago, but > > my reaction at that time was that they were as extensive as they were > > dismaying as they were stupid as they were unenforceable. > > If you go to the order page, > > https://www.wolfram.com/securecheckout/?model=MHED100D&use_type=HomeEdition > > there is the following note > > "Mathematica Home Edition is a 32-bit program available for Windows > (XP/Vista/7), Mac OS X (Intel), and Linux.

It was not entirely clear to me from times when I read this before (year + ago) if the 32-bit limitation was just for the Windows platform, or for Linux and OS X too. >From the quote you give above, it implies that the home editionis indeed 32-bit on all platforms.
