In general, you won't have any significant problems with programs as 64
bit computers run 32 bit software easily.
You could run into the occasional problem, and Win7 has "Compatibility
mode" to handle that.
The biggest problems usually have to do with hardware like printers and
scanners that require 64 bit drivers.

Subject: [PCBUILD] Question 64bit
From: tannis zamora <[log in to unmask]>

Good morning everyone,

I am looking to buy a new Dell Studio 17 laptop with Windows 7. All of
the current machines all list 64 bit.

I am very confused. I have a Dell 2200 laptop and a Dell Dimension 2400
desktop. Everything I have is 32 bit.

What is the difference and what will having 64 bit mean exactly?

Does this mean that all of my software programs will not run on the 64
bit Studio 17? 

Am I going to have to replace all of my favorite software programs? I
just don't know enough about this and am very confused? Not even sure I
am asking the right questions.

Thank you for any help you can give.

tannis z TN
