How to open file with NB extension?

Problems with accessing NB may be due to various reasons. Fortunately, most common problems with NB files can be solved without in-depth IT knowledge, and most importantly, in a matter of minutes. The list below will guide you through the process of addressing the encountered problem.

Step 1. Download and install Mathematica

Install software to open NB file The main and most frequent cause precluding users form opening NB files is that no program that can handle NB files is installed on user’s system. The most obvious solution is to download and install Mathematica or one to the listed programs: CDF Player, Wolfram Research Mathematica, Wolfram CDF Player. Above you will find a complete listing of programs that support NB files, classified according to system platforms for which they are available. If you want to download Mathematica installer in the most secured manner, we suggest you visit Wolfram Research, Inc. website and download from their official repositories.

Step 2. Verify the you have the latest version of Mathematica

Update software that support file extension NBIf the problems with opening NB files still occur even after installing Mathematica, it is possible that you have an outdated version of the software. Check the developer’s website whether a newer version of Mathematica is available. Software developers may implement support for more modern file formats in updated versions of their products. The reason that Mathematica cannot handle files with NB may be that the software is outdated. The latest version of Mathematica should support all file formats that where compatible with older versions of the software.

Step 3. Set the default application to open NB files to Mathematica

3. Ensure that you have appropriate access rights

Some files require elevated access rights to open them. Log out of your current account and log in to an account with sufficient access privileges. Then open the Mathematica Notebook file.

4. Make sure that the system has sufficient resources to run Mathematica

The operating systems may note enough free resources to run the application that support NB files. Close all running programs and try opening the NB file.

5. Check if you have the latest updates to the operating system and drivers

Regularly updated system, drivers, and programs keep your computer secure. This may also prevent problems with Mathematica Notebook files. It is possible that one of the available system or driver updates may solve the problems with NB files affecting older versions of given software.
