Troubleshoot NB Files


Typical NB Opening Challenges

Wolfram Research Mathematica Not Present

When you double-click your NB file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Customarily, this means that Wolfram Research Mathematica is not installed on %%os%%. Your operating system cannot associate your NB with Wolfram Research Mathematica, so double-clicking the file won't work.


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


Obsolete Version of Wolfram Research Mathematica

It is possible that your version of Wolfram Research Mathematica isn't able to open your Mathematica Notebook file due to incompatibility. Installing the latest version of Wolfram Research Mathematica from Wolfram Research is recommended. The primary cause of this problem is that your Mathematica Notebook file was created by a different (newer) version of Wolfram Research Mathematica than what's installed.


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


Primarily, problems experienced when opening NB files are due to having the incorrect version of Wolfram Research Mathematica installed on your computer.


Other NB File Opening Causes

You can still experience errors opening NB files even with the latest version of Wolfram Research Mathematica installed on your PC. There can be other issues - unrelated to software - preventing you from opening NB files. These issues include:

  • Corrupt Windows Registry file path references for NB
  • Corruption of the NB file description inside the Registry
  • Partial installation of Wolfram Research Mathematica that did not fully complete
  • The NB itself is corrupted
  • Your NB has adversely impacted by malware
  • Device drivers for NB-related hardware are out-of-date
  • Windows has inadequate resources to open your Mathematica Notebook file
