How Many Computers Can You Install Adobe Software On?
This is one of the most common questions we get, and the answer may pleasantly surprise you… The place to look to find the answer is the Software License Agreement, also called the EULA. This agreement governs the use of your Adobe product, and is translated into 28 languages within each document. It also covers some basics about product activation.
So, in general, how many systems can you install Adobe software on, including CS5.5? The answer for individuals (as opposed to businesses) in most cases is two. The catch is that both computers must be used only by you and the two systems cannot be used at the same time. This policy was designed so that you could run (say) Creative Suite at home on your desktop PC, as well as while travelling with your laptop. But the types of computers and their usage has blurred so much now that you can just pick any two you own and the product should install and properly activate on both…
For example, here is the key text from the EULA for Photoshop CS5:
2.5 Portable or Home Computer Use. Subject to the important restrictions set forth in Section 2.6 [having to do with volume licensees], the primary user of the Computer on which the Software is installed … may install a second copy of the Software for his or her exclusive use on either a portable Computer or a Computer located at his or her home, provided that the Software on the portable or home Computer is not used at the same time as the Software on the primary Computer.
Generally, for Creative Suite and Adobe Acrobat, the two machines must also be of the same operating system (Windows/Mac), because the software is licensed and delivered for use on a specific platform – unless you buy a “business license“… However some Adobe products like Photoshop Elements and Lightroom are now multi-platform for everyone, meaning you can mix-and-match Windows and Mac OS for your two installations.
Importantly, Adobe defines a computer as “a virtual or physical device,” not just a CPU – so that encompasses running on virtualization platforms such as VMware, Citrix, Parallels, and VirtualBox. The same thing goes for a dual-boot system with a product installed on both partitions, including Apple Boot Camp.
Note that these policies work the same way for Adobe’s Education versions – there is no distinction in this regard… However, one major difference in restrictions for the Student & Teacher Editions is they can be run only on the customer’s privately-owned computer(s).
So there’s your answer for most current Adobe software, although we recommend confirming the terms for your particular product or suite because the license agreements are somewhat different for each package (including Creative Suite, Acrobat, Lightroom, Elements, etc.) and version (CS3, CS4, CS5, CS5.5).
If you’re part of a company or business, and/or need more than one computer running the software at the same time, then you might want to take a look at the online discounts and ease of maintenance available through Adobe’s Volume Licensing Store. There you can save money, time, and headaches for multiple users.






An answer to this may be buried in the conversations above, but I have a new Mac and want to move my second allowable copy of CS5 over to it. I copied all my apps to an external hard drive and then put Photoshop into my new applications folder and it wouldn’t open. It said some files were missing – I think it indicated that I needed to reinstall the software. I suppose it makes sense to I deinstall the software on the original and just reinstall onto my new Mac. Is that right?
Yes Paul, that’s right – copying data and project files is fine, but copying program files in an effort to move Photoshop itself between systems won’t work…
