# What does $LicenseType return on various Wolfram Language desktop evaluation platforms Referring to my question about discriminating between various variants of Mathematica, Wolfram Player etc. I was wondering what the values of $LicenseType


and

MathLinkCallFrontEnd@FrontEndValue["\$NotebookLicenseType"]


in various systems and versions. What I know is that they are

{"Professional","Professional"}


for every (standard licensed) Mathematica version since at least version 7 on Windows and

{"Player Pro","Player Pro"}


on "Wolfram Player Pro" version 9 and "CDF Player Pro" version 10 (despite the name that is the same thing in different versions as far as I know).

for a free player I think the result will be (can't test that right now but have done that for several older versions):

{"Player","Player"}


What I'd be interested to know is what these would return for other variants, like e.g. the home/student/trial/free player etc. It would also be interesting to know what the various variants would return when run in a browser via the browser plugin (although that functionality nowadays seems to be considered "deprecated" as the main browsers plan to not support plugins anymore in the future).

Note: an interesting fact is that using the "File" -> "CDF Preview" will return {"Player","Professional"} for both the "CDF Player" and the "Player Pro" emulation, which most probably is an overview...
