BIOS/HARDDISK serial numbers disappear on Windows
If the serial numbers of BIOS and HARDDISK HostIDs disappear on your Windows machine, you should check if all the drivers for your motherboard are correctly installed. This issue may occur after you have installed new firmware updates, or replaced generic Windows drivers with vendor-specific ones; for example for better OS performance, or to fix bugs.
This is not an LM-X License Manager error, bur rather indicates that the drivers provided by your software vendor do not work properly after update. To resolve this problem, make sure your drivers are correctly installed. Contact your application vendor for details on how to resolve this issue.
