I do not own an adobe product and want a one-time payment licence for students and teachers, what should I get? There are so many licenses to choose from and at least 3 lightroom licenses for students.
If all you are looking for is Lightroom, I would suggest going to your campus computer store. The computer store where I worked had Lightroom in stock. If your store doesn't have it in stock they can order it for you. There is really only one Lightroom 5 license that comes with the standalone version, student or otherwise. The program is identical either way. Licensing for the creative cloud is handled through the web and the payment method, But you aren't concerned about that.
I don't have a campus store but would this standalone lightroom licence work? (the 4th one) https://www.adobe.com/products/catalog/software._sl_id-contentfilter_sl_catalog_sl_educati on_sl_popular.edu.html
