Like any other good software, Adobe Reader receives constant updates, new functionalities and bug fixes. All of them are delivered via software updates. For example, an error 109 dialog box error is shown to have been fixed in a hotfix patch.

2. Select the Repair Installation Option

3. Don’t Open PDFs With the Adobe Acrobat DC Chrome Extension

If you’re utilizing the Adobe Acrobat DC Chrome extension to open PDFs, save the PDF to a folder so you can open it with the Adobe Reader desktop software outside the browser. Adobe’s browser extensions aren’t always as reliable as its standalone software for opening PDFs. A PDF will not open if there’s a corrupted browser plug-in.

4. Download the PDF File Again

It might be the case that there’s something up with the PDF file. If it didn’t download correctly (otherwise a partial download), the PDF might be corrupted. So, if you downloaded the PDF, download it again.

5. Repair the PDF

Error 109 can also be due to a corrupted PDF file. So fixing a corrupted PDF file might fix error 109. You can repair PDF files with the Sejda Repair PDF utility as follows.

  • First, click here to open Sejda Repair PDF in your browser.

  • Click the Upload PDF files button there to select a document to repair.
  • Alternatively, you can click the small arrow on the Upload PDF files button to select a document from cloud storage.
  • Then press the Repair PDF button.

There are also various PDF repair software for Windows. DataNumen PDF Repair, SysTools PDF Recovery and Stellar Phoenix PDF Recovery are a few utilities worth noting. However, those repair utilities aren’t freeware packages.

6. Open the PDF With Alternative Software

If you’re sure the PDF is not in any way corrupted, try opening the document with alternative software. That might not really be a fix for error 109, but alternative PDF software might at least open the document. Foxit Reader is one of the most highly rated freeware alternatives to Adobe Reader that you can open and edit PDFs with. Click the Free Foxit Reader Download on this page to check out that software.
