Troubleshooting Problems Opening HGL Files

Common HGL Opening Problems

Missing CADSoftTools ABViewer

You attempt to load your HGL file and get an error such as "%%os%% Can't Open The HGL File Extension". Generally, this is experienced in %%os%% because CADSoftTools ABViewer isn't installed on your PC. The OS won't know what to do with your HGL file, so double-clicking to load the file doesn't work.

Tip: If you don't have CADSoftTools ABViewer installed, and you know of another program to open your HGL file, you can try opening it by selecting from the programs listed under "Show Apps".

Incorrect CADSoftTools ABViewer Version

Sometimes your installed version of CADSoftTools ABViewer won't support your HP Graphics Language File file. Visit the CADSoftTools website to download (or purchase) the latest version of CADSoftTools ABViewer. This problem is predominately due to having a HP Graphics Language File file version that was created by a newer version of CADSoftTools ABViewer than what you have installed on your PC.

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

Conclusion: The majority of HGL file opening issues are due to not having the correct CADSoftTools ABViewer version installed.
