Troubleshooting Problems Opening AI4 Files

Frequent AI4 Opening Issues

Adobe Illustrator CC Removed

If you attempt to load your AI4 file, you experience a message such as "Can't Open AI4 Files". Generally, this is experienced in %%os%% because Adobe Illustrator CC isn't installed on your PC. The typical path of opening your AI4 with a double-click won't work because %%os%% cannot make the program connection.

Tip: Another AI4-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

In some cases, you might have a newer (or older) version of a Encapsulated PostScript File file that is unsupported by your installed application version. If you've got the wrong version of Adobe Illustrator CC installed, you'll need to install the correct version. This issue mainly occurs when your Encapsulated PostScript File file was created by a newer version of Adobe Illustrator CC than you have on your PC.

Tip: Sometimes you can get a clue about the version of AI4 file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Primarily, problems experienced when opening AI4 files are due to having the incorrect version of Adobe Illustrator CC installed on your computer.

Other AI4 File Issues

Assuming you have the right Adobe Illustrator CC version installed, other problems can prevent you from opening AI4 files. There can be external issues inside of %%os%% that are causing these errors when opening AI4s. Issues that aren't software-related:

• File references in the Windows Registry for AI4 are wrong
• Accidental deletion of the description of the AI4 file in the Windows registry
• Partial installation of Adobe Illustrator CC that did not fully complete
• Your AI4 file is corrupted (issues with your Encapsulated PostScript File file itself)
• Past or present virus infection has affected your AI4
• Hardware related to AI4s has device driver corruption
• Too many applications are open on your PC to load your Encapsulated PostScript File file successfully
