Acrobat me demande chaque fois de me connecter

Hi @WoodyLeChtimi 

Sorry to hear about the trouble caused.

There are 4 different solutions here, https://helpx.adobe.com/download-install/kb/acrobat-repeatedly-prompts-for-sign-in.html surprised that none of the four steps worked here.

Please install Acrobat Pro clean; if that doesn't work, launch the application in a hidden admin account. 

• Run this cleaner tool to remove the existing installer and application’s file traces:

Download the Acrobat installer from here:

Are you running this in an Enterprise environment? 

Thanks,
