Frequent WTR Opening Issues

Microsoft Encarta Isn't There

You encounter an error message such as "%%os%% Can't Open WTR Files" when trying to open your WTR. When this happens, it is commonly due to Microsoft Encarta missing in %%os%%. 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: When you have another program installed that you know will open your WTR, you can select it from the other programs listed (see "Show Apps").

Microsoft Encarta Requires Update

In other instances, your Encarta File file version may not be supported by your version of Microsoft Encarta. If you've got the wrong version of Microsoft Encarta installed, you'll need to install the correct version. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

Tip: Right-clicking on your WTR, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

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