Nikki, You can install the software on two computers with no issue, so go ahead and install on the new computer as Mylenium indicated above. Here is some more information on the topic  in case you are interested: Pattie Purchased Software: A single license for Adobe software lets you install the applications on two computers,  but you can only use the software on one computer at any given time. If you want to install the software on a third computer, deactivate the software on the computer on which you will no longer use the software. Then, activate the software on the new computer. You can install most Adobe software on up to two of your computers, with some qualifications. Creative Cloud: If you are using creative cloud, you can install the apps on your primary computer and one backup computer. You will have access to both the Mac OS and Windows versions, so if you have a Mac at home and a PC at work, for example, you can install your applications on both. See the product license agreements page for more information. Read more in the Creative Cloud FAQ ... View more

Norman- It sounds like you are trying to upgrade to Lightroom CC 2015 and having issues. If you have a complete Creative Cloud membership or a Photography plan, you should be able to download and install Lightroom CC 2015 from the Creative Cloud site. Since Lightroom CC is a new product, it will not show as an update in the Adobe Application Manager. Instead, press the  install button next to Lightroom in the Application manager. If you don't see "install" by Lightroom in the application manager, please first try signing out and back in: sign in and sign out of the Creative Cloud desktop app If you still have issues, see option 2 in this link: Lightroom doesn't launch or quits automatically after splash screen Regards, Pattie ...
