General Synopsys Information:
Setting Environment Variables on Client Systems You must set the environment variables on each client to refer to the license servers to be used.

1. From the Start menu, choose Settings > Control Panel.
2. Double-click the System icon.
3. Click the Environment tab of the System Properties folder.
4. In the Variable field near the bottom, enter the name of the environment variable that you want to set. (For example, type SNPSLMD_LICENSE_FILE.)

Note:
It is recommended that you use the SNPSLMD_LICENSE_FILE variable to refer to the SCL license key file and software. However, you can also (or alternatively) set the standard Macrovision Software, Inc. license environment variable LM_LICENSE_FILE.

5. In the Value field, type the location of the SCL license key file (and server software) using the port@host notation. The following example sets the client to refer to the server at port 1781 whose host name is license: 1781@license
