PFM File Complications

Issues Opening PFM Files

Microsoft Windows Font Viewer Removed

If you attempt to load your PFM file, you experience a message such as "Can't Open PFM Files". When this happens, it is commonly due to Microsoft Windows Font Viewer missing in %%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: Another PFM-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Obsolete Version of Microsoft Windows Font Viewer

Your Printer Font Metrics File file is incompatible with Microsoft Windows Font Viewer because you might have the wrong version installed. If you've got the wrong version of Microsoft Windows Font Viewer installed, you'll need to install the correct version. This problem is predominately due to having a Printer Font Metrics File file version that was created by a newer version of Microsoft Windows Font Viewer than what you have installed on your PC.

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

Summary: Not having the right Microsoft Windows Font Viewer version on your computer can cause problems opening PFM files.
