Troubleshooting Problems Opening OEX Files


Common Problems Opening OEX Files

Opera is Not Installed

When you double-click your OEX file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". If this is the case, it's usually due to the fact that you do not have Opera for %%os%% installed on your computer. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.


Tip: If you know of another program that can open your OEX file, you can try opening it by selecting the application from the programs listed.


Wrong Version of Opera is Installed

In some cases, you might have a newer (or older) version of a Opera browser file that is unsupported by your installed application version. If you do not have the proper version Opera (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: Sometimes you can get a clue about the version of OEX file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Summary: In either case, the majority of problems opening OEX files are related to not having the correct software application installed on your computer.


Other Causes of OEX File Opening Problems

Although you might already have Opera or another OEX-associated software installed on your computer, you can still encounter problems opening Opera browser files. If you are still having problems opening OEX files, there may be other issues that are preventing you from opening these files. These other problems include (listed in order from most to least common):

  • Invalid OEX file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Accidental deletion of the description of the OEX file in the Windows registry
  • Incomplete or bad installation of a software application associated with the OEX format
  • Your OEX file is corrupted (issues with your Opera browser file itself)
  • Your OEX is infected with malware
  • Device drivers of the hardware associated with your OEX file are corrupt or out-of-date
  • Your computer does not have the adequate system resources to open the Opera browser format
