Before installing Sierra, ensure that you are logged into your Windows account with administrative privileges. You will also want to be sure to download and install the latest version of Java. Note that in some cases it may be necessary for your local IT to intervene, especially in cases of firewalls, unprivileged accounts, and the presence of programs such as Deep Freeze.

Issues with installing or running Sierra can be difficult to diagnose and in many cases your local IT will need to be involved. Below are the most common issues.
Local or campus firewalls can block information flowing to Sierra. You will want to ensure that the firewall allows access to the Sierra server, which has the IP address of 220.127.116.11. You will also want to ensure the following ports are not blocked:
|Firewalls - RFC Compliance||
The setting "Enforce strict TCP compliance with RFC 793 and RFC 1122" can cause dropped packets for Sierra. Make sure this setting is disabled. Other settings to disable would be "TCP checksum enforcement" and "TCP handshake timeout". For Sonicwall devices these settings are located under Firewall Settings > Flood Protection.
Other software may interfere or prevent Sierra from installing or running. Start by temporarily disabling firewalls and antivirus software.
|Sierra Won't Load||
Sierra polls the printers visible to your PC at the time of launch. Multiple printers will take longer to check than one or two. Occasionally, a disconnected printer or network printer can cause the Sierra Desktop Client to take several minutes to load, so be sure to remove or disable any printers if appropriate.

The Sierra installer initially asks for a server address. You will want to use cat.opal-libraries.org instead of an IP address. To check or change this entry:
