Shared license with limited uses - can I redownload SOLIDWORKS?

I have access to my school's SOLIDWORKS license at home in order to work on personal projects and assignments. 
However, this license is limited to 20 users and I was instructed not to use any more than necessary. 
I am using a new computer as of now and I have to re-install SOLIDWORKS. 
Will it use up another use of the limited license or is there a way I can re-install SOLIDWORKS without taking up another license slot?
