The ispLEVER software requires a license based on the NIC or physical address of your PC. A Windows environment variable is used to locate the file containing the license information.
Solution:
There are two main causes of a license error:
1.) An incorrect license file - When you request a license, make sure that the NIC or physical address of your PC is correct. The license file is based on the NIC address of your system. You can open the license file with a text editor to verify that the NIC address matches that of your system, but do not edit the file. If you apply for a license using the wrong NIC address, you must request a new one so that the encrypted license numbers are updated.
2.) The LM_LICENSE_FILE variable is improperly set. Open a DOS prompt and type 'set'. This will show you all of your environment variables and their values. Note the value of LM_LICENSE_FILE and make sure it points to your license.dat file. The typical setting for this variable is C:\ispTOOLS7_1\license\license.dat. If there are multiple licenses, make sure that individual license files are separated with a semicolon (;) and NO space after it.
If the variable is improperly set, modify it to point to the correct license file location. To modify the environment variables in Windows 2000, XP or Vista, use the control panel.
Control Panel -> System -> Advanced -> Environment variables
No reboot is necessary.
If the problem still persists, please send the following information to techsupport@latticesemi.com
- What program(s) are failing to operate.
- The License file.
- The values of your environment variables. You can create a file containing these by typing 'set > vars.txt' at a DOS prompt. Send the vars.txt file that is created.
- Indicate the Operating system and install path of ispLEVER.
- The NIC or physical address of your PC. This is twelve digit hexadecimal number, NOT the IP address. You can find the NIC address by opening an MS-DOS window, typing ipconfig/all and pressing Enter.
