if your computer is not connected to the internet the software will run and not ask you for anything
Ok, I spent some time with this and finally figured out how to get it working. I'm still not happy with the company, but here's what I found out.
In order to get the program to run without the initial log-in screen:
1) if you haven't already go to the website and update your account to the new "cloud" version
2) now log-in to that new account
3) download the installer program, install the software
4) bring up Simplify3D - it will ask you to log-in
5) make sure the "remember me" check box is checked - log in
6) start Simplify3d
If your machine is not going to be on the network, it must contain the network adapter that you used to install/log-in etc.
Without that network adapter in your machine (don't have to connect a cable to it, just must be there and enabled), Simplify3D version 3.0 will not run.
I guess I have to go buy a network card for my offline machine and start over.
