BioStar2 SW license is based on a MAC address of a Server PC.
If the server PC has more than 2 Network Interface Chip such as physical LAN and wireless LAN, the license could be deleted by detecting MAC address whenever you restart the PC.
Relevant problem
Can't find the license information from BioStar2 >Settings>Server>License even though I activated the license before.
Solution
1) Use one single MAC address and disable another Network Interface Chip before you activate the license.
2) Contact Suprema Sales Team and then, ask to have another option for multiple NICs when they create BioStar2 SW license.
- To know the recorded your license information, please provide .lic file from the C:\Program Files\BioStar 2(x64)\lic.
