Fix Blank PDF Form Fields and Adobe Acrobat Error 105
Question details
A signed PDF form displays empty fields when opened on another computer, and Adobe Acrobat displays Error 105 when attempting to save the file.

- Product
- Adobe Acrobat / PDF
- Device & OS
- not provided
- Scenario
- The user is trying to view, edit, or save a signed PDF form on a different computer but encounters missing data and save errors.
- Observed behavior
- The interactive form fields appear completely blank instead of displaying the entered data, and Acrobat fails to save any changes, throwing an Error 105 message.
Verify whether the problematic PDF was previously opened or modified using Apple Preview on a Mac, as this is a common cause of PDF form corruption.
Save a Copy of the PDF with a New Name
Bypass file-specific corruption and save errors by duplicating the document under a different name.
Often, a specific file instance becomes locked or structurally corrupted, triggering Error 105 when you try to overwrite it. Saving a fresh copy can rebuild the file structure.
Launch Adobe Acrobat or Adobe Reader and open the problematic PDF file.
Navigate to the 'File' menu at the top left of the screen and select 'Save As'.
Choose a destination folder and enter a completely new file name for the document to ensure it does not overwrite the original.
Click 'Save'. Close the application, open the newly created copy, and attempt to edit or fill the fields to see if the error is resolved.

Avoid Using Apple Preview for PDF Forms
Prevent future PDF corruption by strictly using dedicated PDF editors instead of macOS's default Preview app.
Fill and Save PDF Forms Easily with WPS Office
If your current PDF viewer throws errors or corrupts your file, use WPS Office. The built-in WPS PDF tool allows you to safely open, fill, and save interactive PDF forms without losing data or triggering read/write errors.
- 1. Download and Install: Download WPS Office for free and launch the application on your computer.
- 2. Open the PDF: Click 'Open' and select your problematic PDF form using the WPS PDF tool.
- 3. Fill the Form: Click on the interactive fields to type in your data, or use the 'Fill & Sign' features if needed.
- 4. Save the Document: Go to 'Menu' > 'Save As' to securely export the document without encountering read/write corruption errors.

Frequently Asked Questions
Why do my PDF form fields appear blank on another computer?
This usually happens if the PDF was opened or saved in a non-standard PDF viewer, such as Apple Preview on macOS. These basic viewers often lack full support for interactive forms, which can corrupt the fields and make the data invisible to standard PDF software on other computers.
What does Adobe Acrobat Error 105 mean?
Error 105 is an Acrobat error indicating 'a problem reading this document.' It typically points to file corruption, structural issues, or incompatible elements introduced by a different application that previously saved the PDF.
Can I recover the data from a corrupted PDF form?
Sometimes, opening the file in a different PDF reader or using the 'Save As' function to create a new file can bypass the read error. However, if the file was heavily corrupted by a program like Apple Preview, the data may be permanently lost, and you will need to request a newly filled copy from the sender.
