Hi all, I reinstalled envi4.8_64bit due to some problems I was having. But now it doesn't accept my license file. I had a license file without the DEM extraction module then I requested DEM extraction license and they sent me a separate dat file and I believe this is a server license. I am installing that new license the same way I did with the old one. At the end its opening up LMtools for me to configure server, I guess. At this point I don't know what to do. Do I need to configure server even if I will be the only one who will use that license? When I click on envi to start I get the following error: LICENSE MANAGER: Cannot connect to license server system, The license server manager (lmgrd) has not been started yet, the wrong port@host or license file is being used, or the port or hostname in the license file has been changed. What is wrong? I didn't change anything. Please help. Kay
