Here is what I found most useful for a network install. I install from the dvd on one computer. After that I download the update on that computer, and save it. When you install that, it makes an msi in this folder: C:\Documents and Settings\~username~\Local Settings\Temp. I then download a new ActivManager from the website and install it as well, and it makes an msi in that folder as well. They might be in sub-folders. I then run the ActivManager.msi from a shortcut with a '/passive' and a '/norestart' tag, and it goes through it quickly. If you want default settings in ActivInspire, you can do pretty much the same thing. If you want to change some of the settings you need to make a .mst file with the network installer and have it in the same file with the same name as the .msi file. For example, ActivInspire.mst in the same folder as ActivInspire.msi
