أخي الكريم.. جرب هذه الطريقة:
The crack for IDL 8.0 finally came out. However, it's a server licensing, not just copying the license.dat file to license/ directory and it will work. But, it's only a little different and a bit difficult to setup it to work.
Installation Steps:
(1) Install the IDL 8.0 (or ENVI 4.8) software as normal.
(2) Copy the license.dat (If you do not have it, Google it) to the license/ directory in the installation path.
(3) Edit the line SERVER in license.dat file. e.g.,
SERVER tyf 00e0815cb40f 1700
Only change the second word to the hostname (in my case, it is tyf) of your computer.
(4) Change the Mac address of your ethernet card to "00e0815cb40f".
(5) Start LMTools and make correct settings.
(a) Under "Service/Licnese File" tab, choose "Configuration using Services";
(b) Under "Configure Service" tab, give it a name, select the lmgrd.exe file, pick the modified license.dat file, and specify an output log filename. Also check the "Start Server at Powerup" and "Use Services" checkboxes. Then, click the "Save Service" button.
(c) Under "Start/Stop/Reread" tab, click the "Start Server" button.
Now, it is OK for you to start IDL 8.0. It works!
