You place it in: /usr/local/flexlm/licenses/

It also needs to be renamed to: DL_license.dat

place the softimage.lic on /usr/local/flexlm/licenses but I had to create the folders flexlm/licenses because did not exist in the local folder. But it did not work when I clicked Softimage3D Extreme the console left a message that said "ssty:: invalid argument". 

Then I wrote printenv in the unix shell and it showed me an environment variable LM_LICENSE_FILE =: / var / flexlm / license.dat I think the person that  set up my Hard drive wrote that environment variable  and I do not know if this is affecting that Softimage3D does not work.

How can I solve this problem?
