| Network | 1000 Mbps network required to use Spire Server on a Local Area Network with multiple connected workstations | Gigabit Network |
Light use Spire Sever implementations can use Minimum requirements. However, implementations of 5+ users or a database of 1+ GB, should use Recommended requirements.

Other Installation Considerations
Installing Spire Desktop requires administrative rights to the workstation.
Prior to the installation of either Spire Server or Desktop, it may be necessary to temporarily disable the anti-virus software on the workstation in order to allow the install to complete successfully. One symptom might be that the spired.exe program gets incorrectly quarantined by the AV software, preventing the Spire service from running.
