6. Download the PDF file again

1. Install the latest Adobe Reader

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. If this is your error or not, having the latest and greatest is a good idea.

Did you know that if a PDF file was created in a newer version of Adobe Acrobat Reader than the one you have installed, you might have trouble opening it? Another great idea to keep things updated.

We recommend you download the latest version of Adobe Reader in order to be sure you have it all working.

2. 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 Stellar PDF Repair Tool.

The process is quite simple thanks to the easy-to-use interface. Open Stellar and add your PDF file. You could also add multiple files since batch processing is available.

With the file(s) selected, click on the Repair button to start the process. After that, you can see a preview of the repaired file(s). If everything is ok, save the new file(s) and you are done.

3. Select the Repair installation option

1. Open Adobe Reader.
2. Click Help and select Repair Installation.
3. Restart Windows when Adobe notifies you to do so.

Adobe Reader includes a Repair Installation option that might come in handy for fixing the error 109. That setting repairs the software’s installation files.

4. 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.

5. 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 we strongly recommend using alternative PDF software that might at least open the document.

Not only it will be able to open almost any kind of file you have on your computer, but you can also print and convert files from one format to another.

And if you might need to quickly edit a document or make small changes to a photo, you can do that right within this software.

The latest version provides light and dark themes alongside the new user interface making it a joy to use it.
