How to Fix Acrobat DC Installation Errors 117 and 126 on macOS
Question details
The user is encountering error codes 117 or 126 when attempting to install Adobe Acrobat DC on macOS, preventing successful deployment.
- Product
- Adobe Acrobat DC
- Device & OS
- macOS
- Scenario
- Installing or deploying Acrobat DC in a standard or enterprise Mac environment.
- Observed behavior
- The installation process fails, displaying error 117 or 126 due to the installer's inability to synchronize components, access required background services, or communicate with Adobe's installation servers.
Verify that you have a stable internet connection and that your macOS version is fully compatible with the specific Acrobat DC release you are attempting to install.
Verify Network Connectivity, Firewall, and System Settings
Ensure that your Mac can successfully communicate with Adobe's installation servers without being blocked by system or network restrictions.
Errors 117 and 126 primarily indicate a communication breakdown between the Adobe installer and the necessary server components. Checking your basic system configurations is the most effective first step.
Open System Preferences > Network > Advanced > Proxies, and ensure no unwanted proxy settings are blocking communication. Also verify your firewall settings under Security & Privacy.
Navigate to System Preferences > Date & Time. Ensure that 'Set date and time automatically' is checked, as incorrect system clocks can cause secure server connections to fail.
Ensure you are logged into an macOS account with administrator privileges so the installer can write files to system directories and register necessary services.
Use an Official Enterprise Deployment Package
Avoid browser-based installations and use standalone installer packages provided by Adobe or your IT administrator.
Collect Logs and Contact Adobe Support
If standard troubleshooting fails, gather installation logs to help Adobe Support diagnose the specific deployment issue.

Frequently Asked Questions
What triggers error 117 or 126 during Acrobat DC installation on a Mac?
These errors usually occur when the installer cannot synchronize required components, lacks administrator permissions, or is blocked from communicating with Adobe servers due to network or firewall restrictions.
Why is it recommended to avoid browser-based installations for Acrobat DC?
Browser-based installations sometimes fail to trigger the elevated administrative privileges or specific configurations required for enterprise deployment, resulting in failed service access.
Can incorrect date and time settings on my Mac cause Adobe installation errors?
Yes. If your Mac's date and time are not synchronized correctly with global time servers, the secure HTTPS connections to Adobe's installation servers may be rejected, leading to synchronization failures.
How do I check my proxy settings on macOS Big Sur?
Go to System Preferences, click on Network, select your active connection, and click Advanced. Navigate to the Proxies tab to ensure no incorrect proxy servers are interfering with your internet access.
