Pas de mise à jour possible

You need a newer operating system. 

Make sure your computer meets the minimum CPU & GPU requirements. Most Creative Cloud apps work on these systems, no more than 2 versions back:

• Windows 11 (64-bit) versions 24H2, 23H2; Windows 10 versions 22H2, 21H2;
• MacOS 26 (Tahoe), 15 (Sequoia), 14.7 (Sonoma).
