EOT Troubleshooting

Frequent EOT Opening Issues

Web Embedding Fonts Tool (WEFT) Not Present

You encounter an error message such as "%%os%% Can't Open EOT Files" when trying to open your EOT. Usually, this is because you do not have Web Embedding Fonts Tool (WEFT) for %%os%% installed. Your operating system cannot associate your EOT with Web Embedding Fonts Tool (WEFT), so double-clicking the file won't work.

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

Outdated Web Embedding Fonts Tool (WEFT)

It is possible that your version of Web Embedding Fonts Tool (WEFT) isn't able to open your Embedded OpenType Font file due to incompatibility. Installing the latest version of Web Embedding Fonts Tool (WEFT) from Microsoft Corporation is recommended. This issue mainly occurs when your Embedded OpenType Font file was created by a newer version of Web Embedding Fonts Tool (WEFT) than you have on your PC.

Tip: If you right-click on your EOT file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Ultimately, most of the difficulties opening EOT files are due to having the wrong version of Web Embedding Fonts Tool (WEFT) installed.

Associated Difficulties Loading EOT Files

You can still experience errors opening EOT files even with the latest version of Web Embedding Fonts Tool (WEFT) installed on your PC. There can be external issues inside of %%os%% that are causing these errors when opening EOTs. Issues that aren't software-related:

• Windows Registry EOT file paths that are incorrect
• Unintentional removal of the description of the EOT file inside the Windows Registry
• Corrupt install of Web Embedding Fonts Tool (WEFT) or other EOT-related program
• Your EOT can't be loaded properly (file corruption)
• Your EOT is infected with malware
• EOT-related hardware has device drivers that obsolete
• Too many applications are open on your PC to load your Embedded OpenType Font file successfully
