How to transfer a CS5 license to another PC

The elephant in the room:

15-year-old legacyware that was built to run on Windows XP/Vista/7 is unsupported. It was never retrofitted for use on modern equipment & OSs.

1. The technology is too far apart. 

2. CS5 is not high-DPI aware & thus not suitable for use on hi-res displays. 

3. Internet security protocols have changed.

4. Your user experience will likely be far below expectations, especially on Win11. 

With all that in mind, do have an exit strategy for migrating to modern products.

Given their advanced age, Creative Suite's servers may not be fully functional anymore. Deactivate/Activate at your own risk. 

Most Creative Cloud apps are certified to work on these systems, no more than 2 versions back:

• Windows 11 (64-bit) versions 24H2, 23H2; Windows 10 versions 22H2, 21H2;
• MacOS 15 (Sequoia), 14.7 (Sonoma), 13.6.7 (Ventura).

Good luck.

it will IF your win 10 computer meets adobe's security requirements for conveying that deaction to adobe's computers.  to that end make sure your win 10 os is updated and your default browser is not opera and is updated.  and, of course, it will need an internet connection.

also, there are a variety of items that can block that info from being conveyed to adobe.  if that occurs, you'll lose your win 10 activation but you won't be able to re-use it (other than on that win 10 computer, if that win 10 computer is altered to convey the activation info to adobe).
