i personally could not tell you that...it was my sons and he used to download certain music programs to the computer and he had to get the smart key to down load them and he only used it for one program .
Kinda useless if you cannot figure out what it is... What is an iLok?
The iLok is a USB smart key that holds licenses for participating protected software products. A single iLok can store over 500 separate licenses (2nd Generation), or 118 separate licenses (original iLok). You can have licenses from multiple software publishers on the same iLok, and multiple iLoks can be connected to a computer to authorize software products. With an iLok, you can carry all of your software licenses with you wherever you go. The iLok is portable, convenient and hassle free. So you do not have to right down your program keys if you install on multiple machines...Safe secure storage for license keys...
