Dragon Disappointment

I just tried to install Dragon Naturally Speaking on my home computer and it could not install successfully because I do not have enough RAM on my computer. I purchased my computer in 2003 and it has only 256 MB of RAM--1 GB of RAM is required for installation. Other system requirements for Dragon are a Pentium 4, 2.4 GHz processor, and 800 MB to 2.5 GB free hard disk space if doing a full installation with multiple voice files (650 MB minimum if doing a custom installation with only a few components and one voice file). I have been reading some discussion about Dragon NS--it is very accurate but the voice files are very large and some people have run into problems trying to save such large files. Many of the computers in our district are older and they may not support this program adequately. I probably will be able to install it on my work laptop---will try on Monday.
