I have the boxed version of CS5 Design Premium edition and due to money constraints, was only going to upgrade to the CS5.5 Design Regular edition, that differed primarily with the omission of Dreamweaver. My reasoning at the time was that since I was only a casual user of Dreamweaver, I could just upgrade everything else and that I would easily function with the older version of Dreamweaver until there was a point that I needed to upgrade. But apparently when you "downgrade", the new version of CS5.5 erases your old version of CS5, and with it the other apps that went along with it. That wasn't part of my plan.
My question. So, instead of moving up incrementally every year, I've made the move to the creative cloud. It's just the smart thing to do, but do I erase my old CS5? Will it still work in a year, will I care? it takes up a lot of room and if I can't use it, what's the point. I could always reinstall it some rainy day for kicks. But serriously, what's the point of saving any of it if the creative cloud gives me shiny new versions of everything?
From what I have read in a FAQ and also in several threads, you are able to use your older versions at the same time as the newer version if you want to. Here is a link to the Creative Cloud FAQ : https://www.adobe.com/products/creativecloud/faq.html . You can find this topic about midway down the page.
The decision is yours, but you do have that choice to make.
Hi David - As the user above mentioned, you can indeed have older versions of Adobe products installed on your computer, along with the applications downloaded from Creative Cloud. You retain licenses to individual products you have purchased outside of Creative Cloud, so if you want to remove the CS5.5 applications you have and then reinstall at a later date, you will have no problems at all.
