Apply Adobe's Recommended Browser and OS Updates
Resolve the 'browser or operating system is no longer supported' error by ensuring your system components meet Adobe's legacy activation requirements.
Older versions of Adobe software often rely on legacy browser components (like older Internet Explorer frameworks) to render their sign-in and activation screens. If these components are outdated or disabled on a newer Windows 10 build, the software triggers an update warning.
Check if the dialog specifically says, 'Your browser or operating system is no longer supported—Update Required'.
Go to Windows Settings > Apps > Default apps, and temporarily set Microsoft Edge or Google Chrome as your default web browser.
Navigate to Windows Settings > Update & Security > Windows Update. Click 'Check for updates' to ensure all system frameworks and browser dependencies are fully patched.
Visit the official Adobe Help Center article regarding operating system and browser updates to see if a specific registry fix or patch is required for legacy Acrobat installations.
Contact Support for Legacy Activation
Reach out to Adobe Support for manual assistance, as automated activation for the unsupported 2015 release may no longer function properly.

Frequently Asked Questions
Why does Acrobat Pro DC 2015 show an update required error on a new PC?
This typically occurs because older versions of Acrobat rely on legacy operating system components or outdated browser frameworks (like early versions of Internet Explorer) to load the activation interface. These are often incompatible or disabled on modern Windows 10 installations.
Is Adobe Acrobat 2015 still supported by Adobe?
No, Adobe Acrobat 2015 has reached its end of support. This means Adobe no longer provides security updates, bug fixes, or guaranteed compatibility for newer operating system updates.
Can I still use my perpetual Acrobat 2015 license on Windows 10?
While the perpetual license technically remains valid, hardware and OS changes can break the legacy activation process. If updating your OS and browser doesn't resolve the activation block, you may need to contact Adobe support for a manual workaround or consider switching to a modern PDF reader.
