CNR Troubleshooting


Troubles Opening CNR Files

Pegasus Mail is Not Installed

You encounter an error message such as "%%os%% Can't Open CNR Files" when trying to open your CNR. Usually, this is because you do not have Pegasus Mail for %%os%% installed. The OS won't know what to do with your CNR file, so double-clicking to load the file doesn't work.


Tip: If you don't have Pegasus Mail installed, and you know of another program to open your CNR file, you can try opening it by selecting from the programs listed under "Show Apps".


Wrong Version of Pegasus Mail is Installed

In other instances, your Pegasus Mail Mail Message Stored In Systemwide Folder file version may not be supported by your version of Pegasus Mail. Download the latest Pegasus Mail version from the David Harris website to ensure you have the correct one installed. Your Pegasus Mail Mail Message Stored In Systemwide Folder file was probably created by a newer release of Pegasus Mail than what's currently installed your computer.


Tip: Sometimes you can get a clue about the version of CNR file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Conclusion: The majority of CNR file opening issues are due to not having the correct Pegasus Mail version installed.


More Causes of Problems Opening CNRs

Assuming you have the right Pegasus Mail version installed, other problems can prevent you from opening CNR files. Other CNR opening errors can be created by other system problems inside of %%os%%. Issues that aren't software-related:

  • CNR file references in the Windows Registry are broken
  • Deletion of the CNR file description from the Registry by mistake
  • Partial installation of Pegasus Mail that did not fully complete
  • Something has caused file corruption of your CNR
  • Your CNR has adversely impacted by malware
  • Hardware associated with CNR has outdated drivers
  • Windows has inadequate resources to open your Pegasus Mail Mail Message Stored In Systemwide Folder file

Poll: Do you use a computer or mobile device more often to view files?
