Troubleshooting Problems Opening HP_ Files

Issues Opening HP_ Files

Microsoft Windows Help Isn't There

You encounter an error message such as "%%os%% Can't Open HP_ Files" when trying to open your HP_. Generally, this is experienced in %%os%% because Microsoft Windows Help isn't installed on your PC. The typical path of opening your HP_ with a double-click won't work because %%os%% cannot make the program connection.

Tip: Another HP_-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Incorrect Microsoft Windows Help Version

It is possible that your version of Microsoft Windows Help isn't able to open your Winhelp Compressed File file due to incompatibility. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Windows Help. Most of the time your Winhelp Compressed File file was created by a newer Microsoft Windows Help than what you have installed.

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

Regardless, most of the HP_ file opening problems relate to not having the right version of Microsoft Windows Help installed.
