Hello Folks,
everytime you install the Universal Desktop OS with the IGEL UDC installation dongle the license will be generated from the license smart card and installed into the Universal Desktop OS.
During this process the license will be also saved in the folder \licenses, if you now update the installation dongle with a newer installer Version these licenses will be wiped out. The issue here, if the hard disk is broken in your migrated device you need to apply a new license.
The licenses written on the UDC dongle can be also used thru the IGEL Universal Management Suite license administration console, so you can use the UMS to apply an already created license to a device.
Cheers
Michael
P.S.: Universal Desktop OS licenses are not compatible to Universal Desktop ES or LX firmwares!
