Troubleshoot HWOF Files

Issues Opening HWOF Files

Microsoft Office Removed

You attempt to load your HWOF file and get an error such as "%%os%% Can't Open The HWOF File Extension". Customarily, this means that Microsoft Office is not installed on %%os%%. 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: When another HWOF application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Incorrect Microsoft Office Version

Occasionally, you might have an outdated version of Microsoft Office installed that's incompatible with your Microsoft Office For Mac Help File type. If you've got the wrong version of Microsoft Office installed, you'll need to install the correct version. The primary cause of this problem is that your Microsoft Office For Mac Help File file was created by a different (newer) version of Microsoft Office than what's installed.

Tip: Investigate your HWOF file by right-clicking and selecting "Properties" to find clues on what version you need.

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

Other HWOF File Opening Causes

Even with the correct version of Microsoft Office installed, you can still experience difficulties opening HWOFs. There can be other issues - unrelated to software - preventing you from opening HWOF files. Problems unrelated to software:

• HWOF file type Registry entries are wrong
• The HWOF file description within the Windows Registry was removed
• Defective install of a HWOF program, such as Microsoft Office
• Something has caused file corruption of your HWOF
• The HWOF is infected with a virus
• Drivers associated with HWOF software need to be updated
• Windows has inadequate resources to open your Microsoft Office For Mac Help File file
