Sources of MCF Problems


Troubles Opening MCF Files

Watchtower Library Removed

You attempt to load your MCF file and get an error such as "%%os%% Can't Open The MCF File Extension". Usually, this is because you do not have Watchtower Library for %%os%% installed. The OS won't know what to do with your MCF file, so double-clicking to load the file doesn't work.


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


Incorrect Watchtower Library Version

Your Watchtower Library Font File file is incompatible with Watchtower Library because you might have the wrong version installed. If you've got the wrong version of Watchtower Library installed, you'll need to install the correct version. The primary cause of this problem is that your Watchtower Library Font File file was created by a different (newer) version of Watchtower Library than what's installed.


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


Ultimately, most of the difficulties opening MCF files are due to having the wrong version of Watchtower Library installed.


Additional MCF Opening Issues

Although you might already have Watchtower Library or another MCF-associated software installed on your computer, you can still encounter problems opening Watchtower Library Font File files. Other MCF opening errors can be created by other system problems inside of %%os%%. These issues include:

  • MCF file references in the Windows Registry are broken
  • The MCF file description within the Windows Registry was removed
  • Watchtower Library or another MCF application experienced a flawed installation
  • Your MCF can't be loaded properly (file corruption)
  • Your MCF is infected with malware
  • Device drivers of the hardware associated with your MCF file are corrupt or out-of-date
  • Windows cannot load your Watchtower Library Font File file due to insufficient resources (eg. RAM)
