Troubleshooting Problems Opening BK2 Files


Frequent BK2 Opening Issues

Microsoft Windows Isn't There

When trying to open your BK2 file, you get the error "Can't Open BK2 File Type". When this happens, it is commonly due to Microsoft Windows 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: If you know of another program that can open your BK2 file, you can try opening it by selecting the application from the programs listed.


Obsolete Version of Microsoft Windows

Occasionally, you might have an outdated version of Microsoft Windows installed that's incompatible with your Windows Indexing Service File type. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Windows. 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: If you right-click on your BK2 file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Ultimately, most of the difficulties opening BK2 files are due to having the wrong version of Microsoft Windows installed.


Other BK2 File Opening Causes

Even with the correct version of Microsoft Windows installed, you can still experience difficulties opening BK2s.
