Student 30 day tryal version fully finctionality

[GF_10299512]

I am a student on University of Debrecen, Hungary, and I installed a tryal version of MathCAD with an student licence. unfortunately, something went wrong, because I cannot use all of the functions, for example the Solve function is blocked.
Please helm me to use the fullí functional student tryal version.

 Hi,

1. What version of Mathcad are you using?

2. If you are using Mathcad Prime: "M" button (in the upper left corner of the program) --> "Options" --> "License". Please provide a screenshot of the window.
