HXA Troubleshooting

Typical HXA Opening Challenges

Microsoft Visual Studio Not Present

You attempt to load your HXA file and get an error such as "%%os%% Can't Open The HXA File Extension". If so, it typically means that you don't have Microsoft Visual Studio installed for %%os%%. The OS won't know what to do with your HXA file, so double-clicking to load the file doesn't work.

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

Obsolete Version of Microsoft Visual Studio

Sometimes your installed version of Microsoft Visual Studio won't support your Microsoft Help Attribute Definition file. If you've got the wrong version of Microsoft Visual Studio installed, you'll need to install the correct version. Your Microsoft Help Attribute Definition file was probably created by a newer release of Microsoft Visual Studio than what's currently installed your computer.

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

Summary: Not having the right Microsoft Visual Studio version on your computer can cause problems opening HXA files.

Other HXA File Opening Causes

In the majority of cases, installing the right version of Microsoft Visual Studio will resolve your issue. If you are continuing to have errors with loading HXA files, other external issues might be to blame. These other problems include (listed in order from most to least common):

• HXA file references in the Windows Registry are broken
• Accidental deletion of the description of the HXA file in the Windows registry
• Microsoft Visual Studio or another HXA application experienced a flawed installation
• Your HXA file is corrupted (issues with your Microsoft Help Attribute Definition file itself)
• HXA file integrity has been compromised by malware
• Hardware related to HXAs has device driver corruption
• Too many applications are open on your PC to load your Microsoft Help Attribute Definition file successfully
