I've referred folks to this on the original Legacy DT web site for a good while, but since they seem to no longer pay their web site bill, I have printed this off to a PDF. Kudos to the support guys and folks there for making this reference available on their site for a long time, and perhaps if we can preserve it here, it will answer a LOT of setup questions for folks setting up new PCs.
See attached for some excellent AC, decal and so on setup instructions, esp. noting that the download links here may not be what you expected. Follow it in a detailed fashion and in order, and use the links they suggest, and you'll have a terrific running set of AC/tools, an working setup to the recommended c:\games folder and many other details in nice, working order.
