For most Windows users, Adobe Acrobat is a great tool for creating PDF files. You can edit, print and allow others to access your file collection with this tool.
However, like any other application, this software can sometimes encounter errors. A common problem is that Adobe Acrobat Reader DC does not open PDF files.
So how to handle this problem? Here are 6 fixes you can try to fix Adobe Acrobat Reader DC cannot open PDF files.
Note: Before performing any fixes, make sure that the problem is not just with a PDF file. Check any other files in the software. If all other files work fine, re-download the corrupted PDF or get the file back from the source you obtained earlier.
When you can’t open any PDF files, you can proceed with the fixes below.
1. Run Adobe Acrobat with admin rights
Whenever you run an application with admin rights, that application needs to have full access to all files in the operating system, otherwise the functionality will be limited. Therefore, the first fix you should try is to run Adobe Acrobat Reader with admin rights. If Windows prevents Adobe from opening the PDF file due to missing or faulty permissions, running it as admin will fix the problem.
You can run Adobe Acrobat with admin rights by left-clicking the icon and clicking Run as administrator.
If the software works fine and can open PDFs normally, consider making this setting the default setting for Adobe Acrobat. Follow these steps to configure Adobe to always run with admin rights by default:
B1: Right click on the Adobe shortcut and go to Properties.
B2: Navigate to the tab Shortcut in the window Properties.
B3: Click Advanced.
B4: Check the box Run as administrator and press OK.
Note: Giving admin rights to programs not supported by trusted sources can be dangerous. Always be careful with the programs you give admin rights to.
2. Run Adobe Acrobat in Compatibility Mode
With Windows Compatibility Mode, it is possible to use older versions of Windows as operating systems. There may be some programs that work better with older versions of Windows.
If you are using a version of Adobe that is not compatible with the current version of Windows, run it in Compatibility Mode. To do so, follow these steps:
B1: Right click on the Adobe Acrobat shortcut and go to Properties.
B2: Navigate to the tab Compatibility in the window Properties.
B3: Select check box Compatibility mode.
B4: Choose any old version of Windows from the available options.
B5: Click Apply > OK.
If compatibility issues are the cause, Adobe will start opening PDF files as normal. If not, make sure you’ve turned off Compatibility Mode before performing the rest of the fixes on this list.
3. Turn off Protected Mode
Protected Mode is a security feature introduced in Reader 10.0 to protect users from viruses and attacks. This is a good thing for security, but it sometimes misinterprets files as malicious and doesn’t open them correctly.
Therefore, you can try temporarily disabling this mode to see if it prevents the software from opening PDF files. Here’s how to do it:
B1: Press Win + CHEAP to open Run.
B2: Import Regedit and press Enter to open Registry Editor.
B3: Paste the following address Registry Editor.
ComputerHKEY_LOCAL_MACHINESOFTWAREPoliciesAdobeAdobe AcrobatDCFeatureLockDownB4: Right click and navigate to New > DWORD Value.
Replay the PDF file with Protected Mode turned off. Leave it as it is if everything works fine during this time, instead of having to turn Protected Mode on/off multiple times a day. Of course, this will affect security, so consider your choice!
4. Repair/Update Adobe Acrobat Reader DC
When there are PUP programs, some software and application files may become corrupted. Corrupted files cause Adobe Acrobat to malfunction. Common problems are saving files incorrectly, crashing and the software not loading all PDF files properly.
To make sure this isn’t the problem, repair Adobe Acrobat. This will repair any corrupted files and reinstall any missing files. To repair Adobe Acrobat, follow these steps:
B1: Open Adobe Acrobat Reader DC.
B2: Navigate to the tab Help.
B3: Click Repair Installation.
If the problem persists after a software repair, check for any available updates. Outdated Adobe Acrobat version can also lead to such problem.
To do that, open Adobe Acrobat and navigate to Help > Check for Updates. Adobe will take some time to check for updates and you can update to the latest version if available.
In case none of the measures work, try reinstalling the software.
5. Reinstall the software
Before reinstalling the software, uninstall and delete any associated system files that may still be hidden in the computer.
To do this, go to Control Panel > Programs and Features. Once you have located Adobe Acrobat DC, right click on it and select Uninstall.
Delete the associated system files by visiting the address below on your computer and delete each file.
C:Users<add your username here>AppDataLocalAdobeAcrobatNext, you will need to reinstall the latest version of Adobe from the Adobe website.
Consider switching back to an earlier version of Adobe Acrobat if you’re still having problems even after reinstalling.
6. Roll back to an earlier version of Adobe Acrobat
When a new software version comes out, it often brings a lot of unexpected problems. You can always revert to the old version of Adobe, if the program doesn’t work properly after the update. But before you do that, make sure you uninstall it properly.
Once you’ve finished uninstalling Acrobat, it’s time to download an older version to see if that fixes your problem. Adobe allows you to restore a copy of Acrobat, and you can use third-party sites that host some older files; however, make sure to choose a legitimate source before downloading.
Good luck with your troubleshooting!
