Okay, I've downloaded the 2008 volume 3 installers and installed. So far I haven't had any issues with the products installed and I understand that there isn't a volume 3 version of the AppStylist, but is there supposed to be a upgrade to the SDK?
I noticed this same thing, but there is a installation package with the file name "NetAdvantage_Samples_20083.exe" that was included with the download, and I assume that to be the SDK, but I haven't installed it yet.
I have installed the samples, but the SDK does not appear to be part of that install. In volume 2 the sdk was a separate installation.
