Understanding MRF Issues

Typical MRF Opening Challenges

Missing Apple OS X

If you attempt to load your MRF file, you experience a message such as "Can't Open MRF Files". If this is the case, it's usually due to the fact that you do not have Apple OS X for %%os%% installed on your computer. You won't be able to double-click to open your MRF because your OS doesn't know what to do with it.

Tip: If you know of another program that can open your MRF file, you can try opening it by selecting the application from the programs listed.

Apple OS X Requires Update

Occasionally, you might have an outdated version of Apple OS X installed that's incompatible with your Macintosh Font File type. Installing the latest version of Apple OS X from Apple is recommended. This problem is predominately due to having a Macintosh Font File file version that was created by a newer version of Apple OS X than what you have installed on your PC.

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

Summary: In either case, the majority of problems opening MRF files are related to not having the correct software application installed on your computer.

Additional MRF Opening Issues

Errors opening Macintosh Font File files can still occur even with the latest Apple OS X software installed on your computer. There can be external issues inside of %%os%% that are causing these errors when opening MRFs. Issues that aren't software-related:

• File references in the Windows Registry for MRF are wrong
• Mistaken removal of the Windows registry MRF description
• Incomplete or bad installation of a software application associated with the MRF format
• File corruption affecting your MRF file
• Malware-tainted MRF file can't be opened
• Hardware associated with MRF has outdated drivers
• Too many applications are open on your PC to load your Macintosh Font File file successfully
