Troubleshoot MNG Files
Common MNG Opening Problems
Mozilla Firefox Disappeared
When trying to open your MNG file, you get the error "Can't Open MNG File Type". Usually, this is because you do not have Mozilla Firefox for %%os%% installed. Your operating system cannot associate your MNG with Mozilla Firefox, so double-clicking the file won't work.
Tip: If you don't have Mozilla Firefox installed, and you know of another program to open your MNG file, you can try opening it by selecting from the programs listed under "Show Apps".
Mozilla Firefox Requires Update
It is possible that your version of Mozilla Firefox isn't able to open your Multiple Network Graphic file due to incompatibility. You will need to download a newer version of Mozilla Firefox if you don't have the right version. This issue mainly occurs when your Multiple Network Graphic file was created by a newer version of Mozilla Firefox than you have on your PC.
Tip: Right-clicking on your MNG, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.
Ultimately, most of the difficulties opening MNG files are due to having the wrong version of Mozilla Firefox installed.
Other MNG File Opening Causes
In the majority of cases, installing the right version of Mozilla Firefox will resolve your issue. Other MNG opening errors can be created by other system problems inside of %%os%%. These issues include:
- File references in the Windows Registry for MNG are wrong
- Unintentional removal of the description of the MNG file inside the Windows Registry
- Corrupt install of Mozilla Firefox or other MNG-related program
- File corruption affecting your MNG file
- Your MNG has adversely impacted by malware
- Device drivers for MNG-related hardware are out-of-date
- Your computer does not have the adequate system resources to open the Multiple Network Graphic format
