CFM File Complications

Typical CFM Opening Challenges

Mozilla Firefox Isn't There

When trying to open your CFM file, you get the error "Can't Open CFM File Type". Generally, this is experienced in %%os%% because Mozilla Firefox isn't installed on your PC. The OS won't know what to do with your CFM file, so double-clicking to load the file doesn't work.

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

Outdated Mozilla Firefox

Sometimes your installed version of Mozilla Firefox won't support your ColdFusion Markup File file. If you've got the wrong version of Mozilla Firefox installed, you'll need to install the correct version. This problem is predominately due to having a ColdFusion Markup File file version that was created by a newer version of Mozilla Firefox than what you have installed on your PC.

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

Conclusion: The majority of CFM file opening issues are due to not having the correct Mozilla Firefox version installed.

More Causes of Problems Opening CFMs

Assuming you have the right Mozilla Firefox version installed, other problems can prevent you from opening CFM files. There can be external issues inside of %%os%% that are causing these errors when opening CFMs. These issues include:

• CFM file type Registry entries are wrong
• Accidental deletion of the description of the CFM file in the Windows registry
• Incomplete or bad installation of a software application associated with the CFM format
• The CFM itself is corrupted
• Your CFM is infected with malware
• Device drivers for CFM-related hardware are out-of-date
• Windows has inadequate resources to open your ColdFusion Markup File file
