Sources of WOFF Problems

Common Problems Opening WOFF Files

Internet Explorer Not Present

You attempt to load your WOFF file and get an error such as "%%os%% Can't Open The WOFF File Extension". Customarily, this means that Internet Explorer is not installed on %%os%%. The OS won't know what to do with your WOFF file, so double-clicking to load the file doesn't work.

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

Outdated Internet Explorer

In some cases, you might have a newer (or older) version of a Web Open Font Format File file that is unsupported by your installed application version. Download the latest Internet Explorer version from the Microsoft Corporation website to ensure you have the correct one installed. This issue mainly occurs when your Web Open Font Format File file was created by a newer version of Internet Explorer than you have on your PC.

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

Primarily, problems experienced when opening WOFF files are due to having the incorrect version of Internet Explorer installed on your computer.

More Causes of Problems Opening WOFFs

Assuming you have the right Internet Explorer version installed, other problems can prevent you from opening WOFF files. There can be other issues - unrelated to software - preventing you from opening WOFF files. These issues include:

• File references in the Windows Registry for WOFF are wrong
• The WOFF file description within the Windows Registry was removed
• Internet Explorer or another WOFF application experienced a flawed installation
• The WOFF itself is corrupted
• Past or present virus infection has affected your WOFF
• Device drivers for WOFF-related hardware are out-of-date
• Windows cannot load your Web Open Font Format File file due to insufficient resources (eg. RAM)
