Is it a second serial number or a second installation of the same serial number?

If a single serial number, you may install it on two computers, but are not allowed to use them at the same time.

Moving to Downloading, Installing, Setting Up​

Sure... IF your new computer has a compatible operating system

For Mac El Capitan or the newer Sierra operating system read below

-https://helpx.adobe.com/creative-cloud/kb/install-creative-suite-mac-os-sierra.html

CS6 and earlier programs have not been tested and will not be updated for Mac El Capitan/Sierra

-which means that you try to use CS6 and earlier at YOUR risk of having problems

-you may get CS6 and earlier programs to install and run, or you may not (some do, some don't)

-Java https://helpx.adobe.com/dreamweaver/kb/dreamweaver-java-se-6-runtime.html may help

Install CS5 on Mac 10.11 https://forums.adobe.com/thread/2003455 may help (also for other than CS5)

-also a TEMPORARY security change https://forums.adobe.com/thread/2039319

Cloud & Win10 https://helpx.adobe.com/creative-cloud/kb/Windows_10_compatibility_FAQ.html

-also, only CURRENT products will be tested and updated for compatibility with Windows 10

-so if you have an older program, you update to Windows 10 at YOUR risk of problems

-you may get CS6 and earlier programs to install and run, or you may not (some do, some don't)

An idea that MAY work to install and/or run old programs in Windows 10... works for some, not for others

-RIGHT click the program icon or EXE and select a compatibility mode in the pop up option window

-or Run as Administrator http://forums.adobe.com/thread/969395 to assign FULL Windows permissions may help... says Encore, but sometimes required for ALL Adobe programs (this is NOT the same as using an Administrator account)
