Dear Ada,
any computers you might be buying now are definitely not 32-bit. They
are almost surely 64-bit.
So installing a 32-bit OS is underusing the available resources.
32-bit versions of the modern Windows are designed primarily for
compatibility reasons.
And you will almost surely upgrade your software in the future.
1. Do you have any specific software that will not run in the 64-bit
environment? 32-bit programs work in 64-bit XP and Vista, should be
same with Windows 7. This is not true for the 16-bit programs (Win
3.11 and earlier) - they do not run in Windows 64-bit, but work in
32-bit.
2. Is this the IT policy of your organization to use 32-bit OS? In
this case you may try to pursue the "special needs" route and try to
negotiate an exception.
3. If your data sets grow, how fast? How do you process them? Do you
plan to expand the memory in the future? 32-bit OS will underuse it
(anything after 4gb will not be used).
4. Consult the manufacturer/MSFT regarding upgrade of 32-bit OS to
64-bit OS. It could very well be free.
5. Windows 7 comes with a Virtual XP mode: "Windows XP Mode requires
an additional 1 GB of RAM, an additional 15 GB of available hard disk
space, and a processor capable of hardware virtualization with Intel
VT or AMD-V turned on" so you will not be worse off than you have seen
with XP already. Vista often provides more memory to Stata 10 32-bit
(about 1500mb for me) than XP did (about 1000m for me).
Best regards, Sergiy Radyakin
