    I didn´t success with MLM.exe 64 bits, and i don´t know why. I think my vendor didn´t do anything, becuase it doesn´t start. Could you show me how you find them.

    Thanks kjms

    may be your vendor use long sign. so seed1/2 is useless

    Well they ( Mathworks) are using LONG sign, so ECC will still need to be patched regardless of seed recovery.

    To recover the MLM seeds you can even use the "easy" method.. ( Still works for some daemons)

    Search for constant 3D4DA1D6 and break point each entry .. ( look @ stack or RSP location )
    Seeds are out in the open
    1st break = seed one, 2nd break = seed 2 ... it is a simple as it gets.

    x64dbg command line =
    "C:\Flexlm\Matlab\MLM.exe" -t PCNAME 4 -c c:\flexlm\dummy.dat ( Important that it is called *.dat)

    Use whatever paths you need .. but MLM I've found that it needs to be .dat ( not .lic) ...

    Create a fake license with following :

    SERVER Dune ANY
    VENDOR MLM
    USE_SERVER
    FEATURE Test MLM 99 15-jan-2018 1 1234567890ab \
