Troubleshooting Problems Opening ANNOT Files

Frequent ANNOT Opening Issues

Adobe Digital Editions Not Present

Double-clicking your ANNOT file prompts the message "%%os%% Can't Open ANNOT File". Customarily, this means that Adobe Digital Editions is not installed on %%os%%. You won't be able to double-click to open your ANNOT because your OS doesn't know what to do with it.

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

Incorrect Adobe Digital Editions Version

Sometimes your installed version of Adobe Digital Editions won't support your Adobe Digital Editions Annotations File file. Visit the Adobe Systems Incorporated website to download (or purchase) the latest version of Adobe Digital Editions. This problem is predominately due to having a Adobe Digital Editions Annotations File file version that was created by a newer version of Adobe Digital Editions than what you have installed on your PC.

Tip: You can sometimes get hints about the right program version by right-clicking on the ANNOT file, selecting "Properties", and looking at the version information.

Regardless, most of the ANNOT file opening problems relate to not having the right version of Adobe Digital Editions installed.
