Solution
NI Software for students is subscription based so it is possible that the date of your subscription has passed, hence you will not be able to activate the software. The Student Edition license can only be used for 6 months.
If you are a student of a University with an active Academic Volume License (AVL), you should
get in contact with your IT Help Desk or Service Desk and ask them for the
Student Install Option (SIO) . Use your SIO to activate the NI software.
