Hi Jay,

I too am interested in the answer to your question. I was unable to install
SAS 9.1.3 in a Vista 64 Ultimate machine. The installer came back with an
error message that said something to the effect, "This version of SAS cannot
install to a 64 bit OS" and then returned to the installer. What's
interesting is that I have an old version of SAS 8.2 that I was able to
install to Vista 64.

I've also been able to install WPS 2.2 to XP, Vista 32 and Vista 64 without
any problems. WPS installs as a 32 bit application on my 64 bit machine.

Hi folks,

I know this sounds like a silly query, but having looked at a bunch of
web pages at sas.com I can't seem to distinguish when they're talking
about 32-bit SAS running in a 64-bit environment vs 64-bit SAS running
in a 64-bit environment.

I've worked with SAS for Windows for a long time, but am now reaching
a bottleneck especially in terms of available RAM. Since a 64bit OS
supports much more RAM it seems to make sense to switch to 64-bit SAS
on a 64-bit OS, but just can't decide which OSs 64-bit SAS is
available on. Is there a 64-bit SAS for Win-64? Or Linux? If so, do I
need to buy a different license from the 32-bit license I already
have? I've tried discussing the matter with our SAS rep, but she too
seems to confound the idea of 64-bit SAS with the idea of a 64-bit OS.

She does say that my current 32-bit license is valid for Win-64. If
there's no 64-bit SAS for Windows or Linux, is there any advantage to
running SAS-32 on Win-64? Will it for instance be able to use RAM
beyond 3GB?

Are there any benchmarks out there comparing 32- & 64-bit performance?

TIA,
JW
