the issue you refer to is actually not the installation itself, but the registration.
The registration process itself just need a connection via httpS to the community. This is completly in your hands, or more precisely, the hands of your IT. We can't solve that for you.
I would recommend to contact your IT here. Quite often, there are firewall or proxy restriction due to security reason, which the Express user sometimes does not know.
You must set the proxy settings in the Java Control Panel ( Control Panel -> Java or the command javaws -viewer ).
Enter your proxy under network settings. Enable the setting 'Same proxy server for all protocols' in the advanced menu.
I hope that this setting can solve all of your frustrating problems.
I'm having an issue that every time I launch ARIS Express 2.3 on Mac OSX Lion, the Activation Wizard comes up every time. This is highly annoying. Is there a way to prevent this?
What do you mean with 'Activation Wizard'? The wizzard where you have to enter your ARIS Community login data?
If you mean that ARIS Express downloads something on nearly every startup you should try this workaround:
I find the installation process to be horrible as well. Truly good software shouldn't be this difficult.
The installation of Aris Express on Mac OS X Lion is painful.
It donwloads every time the application from the Internet.
I installed dozens of applications on the Mac, this is the only one that has such a strange behaviour.
I experienced similar behaviour until I installed the latest version of Java... No problems since...
