Issues Opening NAV Files

Missing Quake 3 Arena

You attempt to load your NAV file and get an error such as "%%os%% Can't Open The NAV File Extension". If this is the case, it's usually due to the fact that you do not have Quake 3 Arena for %%os%% installed on your computer. The typical path of opening your NAV with a double-click won't work because %%os%% cannot make the program connection.


Tip: When you have another program installed that you know will open your NAV, you can select it from the other programs listed (see "Show Apps").


Outdated Quake 3 Arena

Your Id Tech 3 Bot Navigation File file is incompatible with Quake 3 Arena because you might have the wrong version installed. If you've got the wrong version of Quake 3 Arena installed, you'll need to install the correct version. Most of the time your Id Tech 3 Bot Navigation File file was created by a newer Quake 3 Arena than what you have installed.


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


Conclusion: The majority of NAV file opening issues are due to not having the correct Quake 3 Arena version installed.


Associated Difficulties Loading NAV Files

In the majority of cases, installing the right version of Quake 3 Arena will resolve your issue. There can be external issues inside of %%os%% that are causing these errors when opening NAVs. Other contributing causes:

  • File references in the Windows Registry for NAV are wrong
  • The NAV file description within the Windows Registry was removed
  • Corrupt install of Quake 3 Arena or other NAV-related program
  • File corruption affecting your NAV file
  • Past or present virus infection has affected your NAV
  • NAV-related hardware has device drivers that obsolete
  • Your computer does not have the adequate system resources to open the Id Tech 3 Bot Navigation File format
