How to Update Adobe Genuine Software Integrity Service Offline
Question details
Users in offline or proxy-restricted enterprise environments need a way to update the Adobe Genuine Software Integrity Service to patch specific security vulnerabilities.

- Product
- Adobe Acrobat / Adobe Genuine Service
- Device & OS
- not provided
- Scenario
- Attempting to update background Adobe software components in offline enterprise deployments or behind strict network proxy servers.
- Observed behavior
- The standard updater fails to update AGSService.exe without internet access, leaving systems exposed to vulnerabilities like CVE-2020-9667, CVE-2020-9668, and CVE-2020-9681.
Ensure you have administrative privileges on the target offline workstations and possess access to your organization's Adobe Enterprise Support portal.
Obtain Offline Installer via Adobe Enterprise Support
Since standard installers require direct internet access, enterprise administrators must request a dedicated offline update package directly from Adobe.
The Adobe Genuine Software Integrity Service (AGSService) relies on an internet connection for standard updates. For air-gapped or proxy-restricted environments, you must use a specialized offline deployment package.
Access your Adobe Admin Console or Enterprise Support portal using your organization's registered administrative credentials.
Create a support request asking for the standalone offline installer specifically for the Adobe Genuine Software Integrity Service.
Explicitly mention the security bulletins (e.g., CVE-2020-9667, CVE-2020-9668) your organization needs to resolve so support provides the correct package version.
Once received, use your organization's standard deployment channels (such as SCCM) to push the offline installer to the affected machines.

Perform a Clean Reinstallation with the Latest Master Package
If a standalone service updater is unavailable, completely reinstalling the entire software suite using an updated full offline master installer is a viable workaround.
Experience Hassle-Free Offline PDF Management with WPS Office
Managing enterprise software deployments and patching background integrity services in offline environments can be highly frustrating. WPS Office offers a lightweight, secure alternative with powerful built-in PDF tools that do not rely on mandatory, internet-dependent background tracking services.

- 2. Install locally without background services: Run the installer. WPS Office installs cleanly without requiring permanent background connectivity utilities.
- 3. Manage your PDFs securely: Open, edit, and save your PDF documents natively within WPS Office while remaining completely offline.

Frequently Asked Questions
What is the Adobe Genuine Software Integrity Service?
It is a background utility (AGSService.exe) installed alongside Adobe products that periodically verifies whether the installed Adobe software is genuine and properly licensed. It requires internet access to check against Adobe's servers.
Why does the AGSService.exe update fail in offline environments?
Standard Adobe update mechanisms are designed to rely on an active internet connection to download security patches directly from Adobe. Strict proxy servers or air-gapped networks block this communication, causing standard updates to fail.
Can I manually delete the AdobeGCClient folder to fix vulnerabilities?
No. Manually deleting or modifying the AdobeGCClient folder or its executable files without official guidance can trigger licensing errors and cause your Adobe applications to shut down unexpectedly.
Are there enterprise alternatives for offline PDF editing?
Yes. Office suites like WPS Office provide robust offline PDF editing and viewing capabilities without enforcing continuous background integrity checks or requiring an internet connection to function securely.
