Troubleshooting Problems Opening XNB Files

Frequent XNB Opening Issues

Microsoft XNA Game Studio Disappeared

If you attempt to load your XNB file, you experience a message such as "Can't Open XNB Files". If so, it typically means that you don't have Microsoft XNA Game Studio installed for %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: When another XNB application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Incorrect Microsoft XNA Game Studio Version

Your XNA Game Studio Binary Package file is incompatible with Microsoft XNA Game Studio because you might have the wrong version installed. If you've got the wrong version of Microsoft XNA Game Studio installed, you'll need to install the correct version. Your XNA Game Studio Binary Package file was probably created by a newer release of Microsoft XNA Game Studio than what's currently installed your computer.

Tip: Right-clicking on your XNB, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

Conclusion: The majority of XNB file opening issues are due to not having the correct Microsoft XNA Game Studio version installed.
