Does off Internet Matlab activation support multiple versions.
显示 更早的评论
Currently, have Matlab 2018b installed, next installed 2012a (all the toolboxes were available for download, now will install 2016a via the instructions at https://www.mathworks.com/matlabcentral/answers/105854
Is this the current process, to have all Matlab and toolboxes available to run off the same license file?

Note: if your using a student license it’s only possible to use only one at a time

That is true sir Walter a staff has given an answer about this see https://www.mathworks.com/matlabcentral/answers/378637-can-i-use-matlab-in-different-computers-with-the-same-license#answer_301934

madhan ravi: that is an answer to a quite different question, dealing with the number of different computers you can use a single Student license on.
Someone who had R2012a, R2016b, and R2018b all on one computer, could use all three versions at the same time on that machine. That would apply whether they were all under the same license or were different licenses.
Furthermore, considering the date differences, those would most likely be different licenses -- especially for Student license, as it was not possible to buy Software Maintenance Service for Student licenses back in R2012a era, so for a Student license the only way to have both R2012a and R2016b would be through separate purchases. (Whereas the R2016b and R2018b would plausibly be the same license, as SMS became available to students around R2016b.)

Each installed version of MATLAB needs its own license file, but you can have multiple versions installed and you can execute multiple versions simultaneously.

If you are using a license server, it can serve multiple licenses off the same port -- this is quite common. In the case of the license server, if I remember correctly (it has been a while) it is common to merge the license files; the license daemon automatically parses to find the end of each one.
For any one license, you only need the newest version of the license file, as all older versions of the same toolboxes are automatically enabled by a newer license.
