Troubleshoot HXL Files

Common Problems Opening HXL Files

Missing Microsoft Windows Help

You attempt to load your HXL file and get an error such as "%%os%% Can't Open The HXL File Extension". Generally, this is experienced in %%os%% because Microsoft Windows Help isn't installed on your PC. Your operating system cannot associate your HXL with Microsoft Windows Help, so double-clicking the file won't work.

Tip: When another HXL application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Incorrect Microsoft Windows Help Version

Sometimes your installed version of Microsoft Windows Help won't support your Microsoft Help Registered Namespace List File file. You will need to download a newer version of Microsoft Windows Help if you don't have the right 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: Find clues on the correct software version by right-clicking your HXL file and clicking "Properties".

Conclusion: The majority of HXL file opening issues are due to not having the correct Microsoft Windows Help version installed.
