J'essaie de télécharger ma 1ère application lightroom sur mon PC, mais après avoir cliquer sur enregoistrer le fichier "creative cloud set up.exe", rien ne se passe (pas de téléchargement, pas de message d'erreur ...).
You have to go to your Downloads folder and Install, RUN, that Setup.exe file.
Not sure what you mean by "Clicking Back"?
You have to Download trhe CC Setup.exe file, locate it on your hard drive (more than likely in your Username Downlaods folder), Run that Setup.exe file and that downloads the CC Desktop app and installs it on your hard drive.
Once that has finished installing it should open. If not then locate it on your Start Menu, or Desktop Shortcut, and open it. From the CC Desktop App you then install LR Classic and Photoshop.
