the license is part of a complicated system with about 8 files. You cannot just copy the files as they are wedded to the computer and wont work on another computer or disk.
Here is a sample of the files involved from http://home.wanadoo.nl/lc.staak/freeme.htm which is a very technical discussion on how it works - for geeks only
Several key DLLs are kept in \windows\system that relate to the MS-DRM scheme.
drmv2clt.dll: Provides basic DRM version 2 functionality
blackbox.dll: Provides basic, machine-specific crypto for MS-DRM. Functionality replaced by IndivBox.key when the local system has been “individualized.”
The other interesting place for files is in \windows\All Users\DRM (this location is not necessarily fixed but comes from the registry entry HKEY_LOCAL_MACHINE\Software\Microsoft\DRM\DataPath). Here’s a sampling of some of the files in this directory (these are hidden system files, so be sure to turn on “view all files” in order to see them!):
IndivBox.key: Despite the extension, this is really a DLL that is an “individualized” version of blackbox.dll
drmv2.lic: The file of licenses (a structured IStorage file)
drmv2.sst: “Secure state” for each of the licenses. Also an IStorage file, but each stream is RC4 encrypted.
v2ks.bla: The version 2 “key store” - this is where all the public/private keys are kept (encrypted, of course!).
v2ksndv.bla: The individualized version 2 “key store.”
