How to Detect if Adobe Acrobat or Reader is 32-Bit or 64-Bit on Windows
Question details
The user needs to find a reliable way to verify the architecture (32-bit vs. 64-bit) of an existing Adobe Acrobat or Reader DC installation for custom deployment purposes.
- Product
- Adobe Acrobat / Reader DC
- Device & OS
- Windows
- Scenario
- Developing or running a custom installer package that requires identifying the architecture of the currently installed PDF reader.
- Observed behavior
- Needs a systematic method to check if the Adobe software is compiled as a 32-bit or 64-bit application.
Verify that your Windows operating system is a 64-bit version first, as a 32-bit operating system can only run 32-bit applications.
Inspect the Executable Architecture Using Task Manager
The most definitive way to determine the application's bit version is to inspect the running executable directly using built-in Windows tools.
Because Adobe embeds the application architecture inside the compiled executable, relying entirely on folder names can sometimes be misleading. Checking the active process via Task Manager yields a definitive result.
Open the Adobe Acrobat or Reader DC application from your Start Menu or desktop shortcut.
Right-click the Windows taskbar and select 'Task Manager', or press Ctrl + Shift + Esc on your keyboard.
Go to the 'Details' tab. Right-click any column header, choose 'Select columns', check the box for 'Platform', and click OK. Locate the 'Acrobat.exe' or 'AcroRd32.exe' process in the list. The 'Platform' column will explicitly state '32-bit' or '64-bit'.
Examine the Installation Folder Path
You can quickly guess the architecture by looking at which 'Program Files' directory the application is installed in on a 64-bit Windows system.
Use the Acrobat DC Customization Wizard
Enterprise administrators can use official Adobe deployment tools to identify versions and customize MSI packages.
Try WPS Office for a Lightweight, All-in-One PDF and Office Solution
If managing heavy 32-bit and 64-bit PDF software deployments is complicating your workflow, consider WPS Office. It provides a lightweight, highly compatible alternative with robust PDF viewing, editing, and conversion features built directly into a complete, easy-to-manage office suite.

- 2. Install WPS Office: Run the setup file. The installer automatically configures the best architecture for your Windows system.
- 3. Manage PDFs Effortlessly: Open WPS Office and select 'PDF' to start viewing, editing, or converting your PDF files without worrying about 32-bit or 64-bit conflicts.
Frequently Asked Questions
Why does it matter whether my PDF reader is 32-bit or 64-bit?
Knowing the correct architecture is crucial when installing plugins, patches, or custom add-ons. A 32-bit plugin will generally fail to load or work properly inside a 64-bit application, and vice versa.
Can I run a 32-bit version of Acrobat on a 64-bit Windows system?
Yes, 64-bit versions of Windows include a subsystem called WOW64 that allows 32-bit applications to run smoothly. However, a native 64-bit application can handle larger files and process complex documents faster.
How do I check if my Windows operating system is 32-bit or 64-bit?
Click the Start button, go to 'Settings', select 'System', and then click 'About'. Under 'Device specifications', look for 'System type' to see whether you have a 32-bit or 64-bit operating system.
