Troubleshooting Problems Opening WBK Files


Issues Opening WBK Files

Microsoft Word Isn't There

You encounter an error message such as "%%os%% Can't Open WBK Files" when trying to open your WBK. When this happens, it is commonly due to Microsoft Word 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: Another WBK-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Obsolete Version of Microsoft Word

Sometimes your installed version of Microsoft Word won't support your Word Document Backup file. Download the latest Microsoft Word version from the Microsoft Corporation website to ensure you have the correct one installed. The primary cause of this problem is that your Word Document Backup file was created by a different (newer) version of Microsoft Word than what's installed.


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


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