Fix Acrobat Sign-in Error: Operating System or Browser Is Out of Date
Question details
Users are unable to sign in to Adobe Acrobat because of a false error message claiming the operating system or browser is outdated.
- Product
- Adobe Acrobat DC and Pro 2017
- Device & OS
- Windows
- Scenario
- Attempting to log into an Adobe Acrobat account in standard or managed enterprise environments.
- Observed behavior
- An error message blocks sign-in by stating the operating system or browser is out of date, even when Windows and all installed web browsers are fully updated to their latest versions.
Verify that your Windows operating system and default web browsers are genuinely up to date. In managed enterprise environments, consult your IT administrator before attempting to modify any system registry settings.
Review Enterprise Security Policies and Adobe Guidance
Check official Adobe documentation and verify your organization's internet security policies, which often restrict Acrobat's ability to connect to sign-in servers.
Visit Adobe's official help page regarding the OS and browser update error to see if any new hotfixes have been released for your specific version of Acrobat.
If you are in a managed enterprise environment, have your IT department verify your browser and Internet security policy settings to ensure Adobe's sign-in domains are whitelisted.
If the issue persists despite policy adjustments, collect your system logs and escalate the open support ticket directly to Adobe Enterprise Support.
Adjust Windows Registry Settings (IT Professionals Only)
Modify the Internet Settings registry key to bypass specific security blocks, which has provided intermittent success for affected enterprise users.

Frequently Asked Questions
Why does Acrobat say my browser is out of date when it is fully updated?
This false error is often caused by conflicts with enterprise security policies, outdated Internet Explorer components lingering in Windows, or restrictive registry settings that prevent Acrobat from securely connecting to Adobe's sign-in servers.
Can I use Acrobat DC without signing in?
Adobe Acrobat DC requires an active subscription and periodic sign-in to verify your license. If the sign-in fails or is bypassed for too long, the software will eventually restrict access to premium editing features.
What should I do if the registry fix doesn't work?
If changing the 'Security_HKLM_Only' registry value does not resolve the issue, immediately revert the value back to its original state to maintain system security. Then, collect your system error logs and escalate the issue to Adobe Enterprise Support.
