How to Upgrade Adobe Acrobat to a 64-Bit Version
Question details
Users need to upgrade their Adobe Acrobat installation to a fully 64-bit version to resolve system compatibility warnings.
- Product
- Adobe Acrobat
- Device & OS
- macOS and Windows
- Scenario
- The user is transitioning to a newer operating system that strictly requires 64-bit applications, triggering software compatibility alerts.
- Observed behavior
- The system displays warnings indicating that Acrobat, or some of its installer components, are not optimized for the Mac and are running as 32-bit.
Before upgrading, check your computer's system information to confirm your current operating system version, as modern OS environments like macOS Catalina and later exclusively support 64-bit applications.
Update to the Latest Acrobat Version
Updating to the most recent release ensures that the core Acrobat application runs as a native 64-bit process on your operating system.
While modern versions of Adobe Acrobat for Mac operate primarily as 64-bit applications, you may still see a warning because specific background installer components remain 32-bit. Adobe is transitioning toward a completely 64-bit architecture to meet the strict requirements of recent operating systems.
Launch your current version of Adobe Acrobat from your applications folder.
Navigate to the top menu bar, click on 'Help', and select 'Check for Updates' from the dropdown list.
Follow the on-screen prompts in the Adobe Updater window to download and install the latest available version.

Frequently Asked Questions
Why does my Mac say Adobe Acrobat is not optimized?
This warning appears because Apple requires all software to be fully 64-bit. While the main Acrobat application is 64-bit, some hidden installer or background components might still be 32-bit, triggering the system alert.
How can I check if my current software is 32-bit or 64-bit?
On a Mac, click the Apple menu, go to 'About This Mac', select 'System Report', and check the 'Applications' section under Software to view the architecture. On Windows, open the Task Manager and look for '(32-bit)' next to the process name.
Can I run 32-bit PDF applications on macOS Catalina or later?
No, macOS Catalina (10.15) and all subsequent versions dropped support for 32-bit applications entirely. You must use 64-bit software to open and edit your PDF files on these operating systems.
