Hi Tein2014, You may install software on up to two computers. These two computers can be Windows, Mac OS, or one each. If you install on a third computer, it will request you to de-activate on the other two computers. You can then reactivate one of the previous two computers, and use Creative Cloud apps on it. Same issue has been discussed in the mentioned link How many computers can I install my Creative Cloud apps on? Let me know if you need further assistance on this, P.S - If this or any other response helps answer your question, please take a moment to mark the response as helpful or correct to make it easier for future users to find the solution to the same issue Thanks, Eshant Jindal
