Understanding HSH Issues

Frequent HSH Opening Issues

Microsoft Windows is Not Installed

You attempt to load your HSH file and get an error such as "%%os%% Can't Open The HSH File Extension". Generally, this is experienced in %%os%% because Microsoft Windows isn't installed on your PC. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: If you have another software that you know opens HSH files, you can select it by hitting the "Show Apps" button.

Obsolete Version of Microsoft Windows

Sometimes your installed version of Microsoft Windows won't support your Windows Catalog Search Index File file. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Windows. This issue mainly occurs when your Windows Catalog Search Index File file was created by a newer version of Microsoft Windows than you have on your PC.

Tip: Find clues on the correct software version by right-clicking your HSH file and clicking "Properties".

Ultimately, most of the difficulties opening HSH files are due to having the wrong version of Microsoft Windows installed.

Associated Difficulties Loading HSH Files

You can still experience errors opening HSH files even with the latest version of Microsoft Windows installed on your PC. If you are continuing to have errors with loading HSH files, other external issues might be to blame. Other contributing causes:

• Invalid HSH file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Accidental deletion of the description of the HSH file in the Windows registry
• Invalid installation of a HSH-associated program (eg. Microsoft Windows)
• HSH file corruption
• Your HSH has adversely impacted by malware
• Drivers associated with HSH software need to be updated
• Too many applications are open on your PC to load your Windows Catalog Search Index File file successfully
