Does 32-Bit Adobe Acrobat Work on 64-Bit Windows? (Fix Legal Paper Printing)
Question details
The user wants to know if a 32-bit Acrobat installation functions correctly on a 64-bit Windows system, as they are experiencing a printing error where documents default to legal size paper instead of standard letter size.

- Product
- Adobe Acrobat
- Device & OS
- 64-bit Windows
- Scenario
- Printing a standard PDF document to a local or network printer.
- Observed behavior
- The printer outputs the PDF document on legal size paper rather than standard letter size, leading the user to suspect a software architecture compatibility issue.
Ensure your printer is properly loaded with letter-sized paper and that you have the necessary administrative privileges in Windows to modify default printer preferences.
Adjust PDF Print Page Sizing Settings
Since 32-bit Adobe Acrobat is completely compatible with 64-bit Windows, the printing anomaly is usually caused by the application's internal print dialog settings rather than the software architecture.
Windows 64-bit includes a subsystem (WOW64) specifically designed to run 32-bit applications seamlessly. The issue of printing to legal paper usually occurs when the PDF's native page size overrides the printer's default settings.
Launch Adobe Acrobat, open your PDF document, and navigate to 'File' > 'Print' or press Ctrl+P.
In the Print dialog box, locate the 'Page Sizing & Handling' section and uncheck the box labeled 'Choose paper source by PDF page size'.
Select the 'Fit' or 'Shrink oversized pages' option under Page Sizing to ensure the document scales correctly to your printer's default paper.
Click the 'Print' button at the bottom right to send the job to the printer and verify it prints on standard letter-sized paper.

Configure Default Windows Printer Preferences
If adjusting Acrobat's settings does not resolve the issue, the printer driver itself might be defaulting to legal paper size at the system level.

- 2. Access the Print Menu: Click the 'Print' icon on the top toolbar or press Ctrl+P on your keyboard.
- 3. Select Letter Size: In the print dialog, ensure the paper size is set to 'Letter' and that the scaling is set to fit the printable area.
- 4. Print Successfully: Click 'Print' to output your document correctly without legal-size paper errors.

Frequently Asked Questions
Why does my printer keep asking for legal size paper when printing PDFs?
This happens when the PDF was originally created with legal-size dimensions and your PDF reader is set to 'Choose paper source by PDF page size'. Disabling this setting in your print dialog forces the printer to use your default paper tray.
Are there any performance issues when running 32-bit software on a 64-bit Windows PC?
Generally, no. Windows uses a built-in emulator called WOW64 that allows 32-bit programs to run efficiently on 64-bit architectures without noticeable performance drops or compatibility errors.
How do I check if my Windows is 32-bit or 64-bit?
You can check your system architecture by pressing the Windows Key + Pause/Break, or by navigating to Settings > System > About. Look for the 'System type' field, which will explicitly state if you are running a 64-bit operating system.
