i have solidworks student edition on my computer. It is a single user license and it expires at the end of the year. However, solidworks opens license manager and tries to get me to activate my license. If I do it I does not work. If I try to activate the license or click cancel solidworks says "the student edition has expired." then it says to go online and buy a new license. This has happened to me before and I found the solution before online except I can't find it. I remember having to go somewhere and deleting a file the contained all my license information. It even reset the free 30 day trial. I have attached a picture of it.
