Troubleshooting Problems Opening B4U Files

Issues Opening B4U Files

docPointer Removed

You attempt to load your B4U file and get an error such as "%%os%% Can't Open The B4U File Extension". If so, it typically means that you don't have docPointer installed for %%os%%. Your operating system cannot associate your B4U with docPointer, so double-clicking the file won't work.

Tip: If you know of another program that can open your B4U file, you can try opening it by selecting the application from the programs listed.

docPointer Requires Update

It is possible that your version of docPointer isn't able to open your Visual ReadMe Data File file due to incompatibility. Download the latest docPointer version from the Open Source website to ensure you have the correct one installed. The primary cause of this problem is that your Visual ReadMe Data File file was created by a different (newer) version of docPointer than what's installed.

Tip: If you right-click on your B4U file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Conclusion: The majority of B4U file opening issues are due to not having the correct docPointer version installed.
