Troubleshoot COF Files


Issues Opening COF Files

MPLAB IDE Not Present

When you double-click your COF file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Generally, this is experienced in %%os%% because MPLAB IDE isn't installed on your PC. Your operating system cannot associate your COF with MPLAB IDE, so double-clicking the file won't work.


Tip: If you have another software that you know opens COF files, you can select it by hitting the "Show Apps" button.


Incorrect MPLAB IDE Version

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


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


Regardless, most of the COF file opening problems relate to not having the right version of MPLAB IDE installed.


More Causes of Problems Opening COFs

You can still experience errors opening COF files even with the latest version of MPLAB IDE installed on your PC. There can be other issues - unrelated to software - preventing you from opening COF files. Problems unrelated to software:

  • Corrupt Windows Registry file path references for COF
  • Accidental deletion of the description of the COF file in the Windows registry
  • Defective install of a COF program, such as MPLAB IDE
  • Your COF can't be loaded properly (file corruption)
  • COF file integrity has been compromised by malware
  • Hardware related to COFs has device driver corruption
  • Windows cannot load your MPLAB COFF File file due to insufficient resources (eg. RAM)
