Hi Sergiy,

Thank you so much for your detailed reply.

I am considering buying a couple of PCs to replace older PCs within my
department, and I was wondering what I needed to get.  Originally I
was pulling my hair out because my university used to charge a £700
per PC on top of hardware and software for looking after a 64 bit
machine.  As we are looking to replace about 6 to 8 PCs it's going to
cost us a considerate amount of money!  I have asked the IT dept again
about this charge since I wrote the email to Statalist and they said
they have now waived this charge (YAY!!!)

So it looks like the problems are resolving on their own - and
hopefully it will go on that direction.

I have only recently used Windows Vista and I haven't yet tried to
push the Stata memory limit on that platform, so it's good to know
what you have told me.  My university does not support Windows Vista
and we are still using XP - I am guessing that they may skip the Vista
and directly upgrade from XP to Windows 7.  I have a Vista machine at
home, so I will try what you've said in your email.

Warm regards,
Ada
