Running the Installer Twice

After installing the software, DO NOT run the installer again. Attempting to do so will cause the software to be automatically uninstalled without asking, and will require users to run it a third time to re-install the program. If you do need to re-install the program, manually uninstall it first, then install it again.

Installation Problems

The VPN Client will not install properly on most machines that are running virus scanning utilities (such as Norton or CUantivirus) or on Windows machines running Internet Connection Sharing. Instructions for turning off virus scanning utilities is specific to the software.

• Instructions for setting CUantivirus to snooze can be found here.

VPN Connectivity Issues after Installing

The VPN Client will not function properly (or at all) with firewall software, other than the basic Windows XP firewall ,running. Likewise, it will not function properly with Internet Connection Sharing runing (if re-installed after removal). Make sure these are both disabled. While there are standard ports generally in use while the client is running, changes may require different port usage, so user specific firewall settings are not supported nor are any third party firewalls (i.e. BlackICE or Norton).

• Instructions for disabling Internet Connection Sharing (ICS).
