Issues Opening LEX Files

Adobe Illustrator CC Not Present

When trying to open your LEX file, you get the error "Can't Open LEX File Type". 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. 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 don't have Adobe Illustrator CC installed, and you know of another program to open your LEX file, you can try opening it by selecting from the programs listed under "Show Apps".

Incorrect Adobe Illustrator CC Version

In some cases, you might have a newer (or older) version of a Adobe Linguistic Library Data File file that is unsupported by your installed application version. Visit the Adobe Systems Incorporated website to download (or purchase) the latest version of Adobe Illustrator CC. This issue mainly occurs when your Adobe Linguistic Library Data File file was created by a newer version of Adobe Illustrator CC than you have on your PC.

Tip: If you right-click on your LEX file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Ultimately, most of the difficulties opening LEX files are due to having the wrong version of Adobe Illustrator CC installed.
