Question details
The user is experiencing Error 20225 when trying to install the Adobe PDF printer via Acrobat 8 on a 64-bit operating system, causing PDF conversion features to fail.

- Product
- Adobe Acrobat 8
- Device & OS
- 64-bit Windows Vista / Windows XP
- Scenario
- Installing Adobe Acrobat 8 to utilize the Adobe PDF printer for document conversion.
- Observed behavior
- The installation triggers Error 20225 and fails to install the Adobe PDF printer, which subsequently prevents several Acrobat conversion features from working.
Check your computer's system properties to confirm whether you are running a 32-bit or 64-bit version of Windows. Keep in mind that older software versions often have strict compatibility limitations with 64-bit architectures.
Install on a 32-Bit OS or Upgrade Your PDF Software
Since Acrobat 8 does not support 64-bit Windows XP or Vista, you must either install the software on a supported 32-bit operating system or upgrade to a modern PDF solution.
Acrobat 8 is an obsolete version that was not designed to support 64-bit versions of Windows XP or Vista. Because the Adobe PDF printer driver is incompatible with 64-bit architectures, the installation fails with Error 20225.
Without the Adobe PDF printer, most conversion components in Acrobat 8 cannot function. Continuing to use obsolete software also poses security risks for sensitive PDF workflows.
Right-click on 'Computer' or 'My Computer' on your desktop or Start menu, and select 'Properties' to confirm your system type (32-bit or 64-bit).
If you must use Acrobat 8, prepare a machine or virtual machine running a supported 32-bit operating system, such as 32-bit Windows XP.
Insert your Acrobat 8 installation media into the 32-bit system and follow the on-screen prompts to complete the installation without the 64-bit driver error.
Alternatively, purchase and download a modern, supported PDF management software that is fully compatible with 64-bit operating systems to avoid installation errors entirely.

Create and Convert PDFs Easily with WPS Office
Instead of struggling with obsolete software and installation errors on 64-bit systems, use WPS Office. It includes a built-in PDF tool that fully supports modern 64-bit operating systems, allowing you to print, edit, and convert PDFs seamlessly without installing third-party virtual printers.
- 1. Install WPS Office: Download and install WPS Office on your 64-bit Windows computer.
- 2. Open your document: Open the document you want to convert in WPS Writer, Spreadsheet, or Presentation.
- 3. Access the export tool: Click on the 'Menu' button in the top-left corner and select 'Export to PDF'.
- 4. Export the file: Adjust your export settings in the dialog box and click 'Export' to instantly create a high-quality PDF file.

Frequently Asked Questions
Why do I get Error 20225 when installing Acrobat 8?
Error 20225 occurs because Acrobat 8 is an older software version that lacks the necessary 64-bit drivers to install the Adobe PDF printer on 64-bit versions of Windows XP and Vista.
Can I force the Adobe PDF printer to install on 64-bit Vista?
No, there is no official workaround to force the Acrobat 8 PDF printer to install on a 64-bit Windows XP or Vista system. You must use a 32-bit OS or upgrade your PDF software to a compatible version.
Do I need an older version installed to upgrade Acrobat?
If you purchased an upgrade version of Acrobat, the installer will typically prompt you to insert the installation CD of your previous qualifying version (like Acrobat 5, 6, or 7) to verify your upgrade eligibility during setup.
Are there alternative ways to print to PDF without Adobe?
Yes, modern operating systems like Windows 10 and 11 include a built-in 'Microsoft Print to PDF' feature. Additionally, modern office suites like WPS Office have native 'Export to PDF' functions that do not require a separate virtual printer.
