Yes based on the explanation above '. This error may be the result of formatting problems in your license file. In order to avoid this, ensure that the following strings all begin on a left justified line: #, SERVER, DAEMON, or INCREMENT.' I checked the Licence File and I do not think the problem is because of that. How can I make sure that I have not already bought this toolbox, because apparently I do not want to but it twice! I tried to use the trial version of this toolbox however during the installation it says:'this tool box is already installed.' So I assumed I already have this tool box!
You would need to buy a license from Mathworks. You should check with Mathworks sales as I am not sure if you are within the range of time where they permit licenses to be purchased for older releases. I suspect that you might be too late. Mathworks might ask you to pay two years of support contract to bring your support to present and then you would purchase the license against the current version, which would entitle you to use previous versions as well. (Situation might get messy if you are a student; I have never been clear on the rules for students accessing previous versions)to comment.
Error 5: Cannot talk to the license server on host ' xxx.x.x.x '. Server not running. The /etc/hosts file might not contain an entry for hostname and IP address. After installing the license information and then attempting to run ENVI or IDL the following error message appears:% LICENSE MANAGER: No such feature.
