I Merged this thread from the Q&A
Hi Jorge,
Is it the “Student” [free] or the “Student/Teacher” [price vary] version?
https://www.maxon.net/en/training/student-version/
The free version has no option for plug-ins.
For the serial code, please contact MAXON directly. Perhaps follow the link above, your country, and fill in the problem perhaps in the “Please explain the roleā¦” field.
Please note that I’m not familiar nor connected to this part of the distribution and I might be wrong.
I hope things will work out fine for you. (I have as well answered your PM.)
All the best
