This question has probably been posted multiple times, but I still cannot find the answer with 100% certainty. I purchased Parallels Desktop 13 Home Edition, Product Code PDFM13L-BX1-EU and then realized that I didn't need it. I paid 74 CHF for it with a discount through my university, so I assume it is the version that usually goes for 79.99 CHF. Do I have a one-time installation version or one that you have to pay yearly to renew? I'm trying to sell it and I need to know this so that I can tell whoever's buying it. Thanks!
