Frequently Asked Questions
Why does Adobe Acrobat DC keep asking for a sign-in?
This usually occurs if the local licensing store becomes corrupted, if browser cookies block the login token, or if an older volume license fails to synchronize properly with Adobe's activation servers after an offline activation attempt.
Can I fix the Acrobat activation loop without contacting support?
Sometimes clearing your browser cache and cookies or reinstalling the application can help. However, for Acrobat DC 2015 volume licenses stuck in an offline activation loop, a manual reset by an Adobe support agent is frequently the only permanent fix.
Does a volume license require a continuous internet connection?
While offline activation is available for volume licenses in secure environments, periodic background verification checks might trigger activation loops if the system struggles to validate the serial number locally or detects anomalies.
