Understanding EBO Issues

Frequent EBO Opening Issues

Missing Microsoft Reader

You attempt to load your EBO file and get an error such as "%%os%% Can't Open The EBO File Extension". Generally, this is experienced in %%os%% because Microsoft Reader isn't installed on your PC. You won't be able to double-click to open your EBO because your OS doesn't know what to do with it.

Tip: When you have another program installed that you know will open your EBO, you can select it from the other programs listed (see "Show Apps").

Incorrect Microsoft Reader Version

In some cases, you might have a newer (or older) version of a Microsoft Reader eBook Format file that is unsupported by your installed application version. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Reader. Your Microsoft Reader eBook Format file was probably created by a newer release of Microsoft Reader than what's currently installed your computer.

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

Conclusion: The majority of EBO file opening issues are due to not having the correct Microsoft Reader version installed.
