Why PDF Files won’t open?
You love using Adobe Reader to open pdf files on your Windows Desktop. However, not being able to access PDF while using an Adobe Systems tool or google chrome is extremely irritating.
As inventors of PDF format, Adobe has a relatively clear understanding of how to optimize users’ experience, especially when engaging in Acrobat premium models.
Why are troublesome?
One of the legit reasons behind the failure of some PDF documents is that the designers are more focused on producing good layouts rather than creating actual proofs. Don’t look at these; they’re going directly to the department or printer.
If designers focus more on open pdf files, then this type of errors can be solved. This means there is far more continuity between the supplied file and the original one.
Why won’t PDF files open? The Causes:
Several reasons prevent the pdf files from opening. We have listed them below:
- The file you are trying to access is either corrupt or damaged.
- One of the reasons your PDF file won’t open is that you might be using an outdated version of Adobe reader.
- The installation process was not completed correctly.
- The PDF document you are trying to access is from a non-Adobe program.
What’s the solution?
1. Update Adobe Acrobat:
If you are using an outdated version of Adobe Acrobat, to open PDF files may not be in a good position. Adobe regularly updates its Apps.
Of this purpose, we can only suggest you access the app from the official Adobe release website.
While there, pick the latest edition of the OS program, and push the Update Now icon. It is more likely that taking the new Update would resolve problems with the program. If the current one is corrupted, that will make a huge difference.
Besides, the new fixes and protection updates will keep Adobe Acrobat still working smoothly.
2. Proper Installation:
There are several ways that a failed download can manifest itself. The process can refuse to begin when you start the download, or the download can end abruptly. The installation can even end with an error message until the full download of the installation package.
- Attempt to resume download again. Before downloading, select the latest version of Adobe Acrobat from the drop-down list on the Downloads page.
- Make sure you’re on secure internet service. Run a compatibility scan to ensure that nothing interferes with your connection, and then restart the Update.
3. Ask the sender to resend the PDF file if it’s damaged:
This is not a particularly common issue, although it is likely that the software used to produce the PDF file didn’t correctly create it. The information in the PDF documents are sometimes damaged and corrupted.
Besides, if the document is sent via email or a website, then the root cause is that it may not be correctly uploaded.
You can check the credibility of the document and whether it is uncorrupted by simply opening another file. If that file opens, then you will know that the other one was corrupted.
4. Use older version for non-adobe files:
Often on your Windows 10 PC, you can attempt to open multiple PDF files, and they struggle to open because they were produced from non-Adobe goods.
PDF documents produced by non-Adobe items do not always follow the PDF requirements and specifications. The reason is that the previous versions of Adobe reader are not so rigid as compared to the latest ones.
The file that you opened by using the older version cannot be opened with the latest version. When you have an idea that the file maker is credible enough, then you can request them to switch to the older version of acrobat reader to open the file.
Moving back to an earlier version would allow you to uninstall the update that’s already installed on your drive.
5. PDF not recognizable
In some instances, when submitted by e-mail, the file extension Microsoft Windows uses to define the file as a PDF can be omitted. Microsoft Windows won’t realize how to access this file because the file doesn’t finish in.pdf. Below is some solution on how to fix this problem.
- Save your PDF to your personal computer.
- From the start menu, you can view the option to enable the browser for PDF.
- Drag the saved PDF into the viewer from the laptop. If this file is uncorrupted and valid, it should be accessed.
Why PDF won’t open in Chrome
The main reason is that google Chrome downloads the document. To fix this just do the following steps:
- Open Google Chrome
- Click on settings
- Then, on Advanced.
- Click on Content Settings (you will find it in the securty and privacy section).
- Search for “PDF Documents”.
- Select the option. “Download PDF files instead of Automatically Opening them”.
If these steps don’t resolve the issue update your chrome version, use another browser or use adobe acrobat reader app.
Many of the difficulties you’ll find while opening PDF files are attributable to one of the above-described causes.
Another important factor is that your PC must have the software to recognize PDF files.
There is a drawback in Window’s 10 and that is it uses Microsoft Edge as the default PDF viewer. It would be best if you altered it to make Acrobat your default viewer.
