Troubleshoot AI Files


Troubles Opening AI Files

Adobe Illustrator CC Isn't There

Double-clicking your AI file prompts the message "%%os%% Can't Open AI File". If this is the case, it's usually due to the fact that you do not have Adobe Illustrator CC for %%os%% installed on your computer. The OS won't know what to do with your AI file, so double-clicking to load the file doesn't work.


Tip: Another AI-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Wrong Version of Adobe Illustrator CC is Installed

Occasionally, you might have an outdated version of Adobe Illustrator CC installed that's incompatible with your Adobe Illustrator File type. You will need to download a newer version of Adobe Illustrator CC if you don't have the right version. Your Adobe Illustrator File file was probably created by a newer release of Adobe Illustrator CC than what's currently installed your computer.


Tip: Investigate your AI file by right-clicking and selecting "Properties" to find clues on what version you need.


Conclusion: The majority of AI file opening issues are due to not having the correct Adobe Illustrator CC version installed.


More Causes of Problems Opening AIs

Assuming you have the right Adobe Illustrator CC version installed, other problems can prevent you from opening AI files. If you are still having problems opening AI files, there may be other issues that are preventing you from opening these files. Problems unrelated to software:

  • File references in the Windows Registry for AI are wrong
  • Unintentional removal of the description of the AI file inside the Windows Registry
  • Invalid installation of a AI-associated program (eg. Adobe Illustrator CC)
  • The AI itself is corrupted
  • Past or present virus infection has affected your AI
  • Drivers associated with AI software need to be updated
  • Windows has inadequate resources to open your Adobe Illustrator File file
