Hello. If you are going to run a 32-bit operating system on a 64-bit processor Jaws for Windows 32-bit will run. However if you are going to run Vista 64-bit you will need to install the 64-bit version of Jaws for Windows which you will either need to download from the web or purchase a CD-ROM. I hope this helps.

I am looking at getting a new laptop and I found an Acer but it has the 64 bit processor. I also want to run XP Home, not Pro on it. Cy, The Anasazi
