Troubleshoot NED Files

Common Problems Opening NED Files

OMNeT++ Removed

You attempt to load your NED file and get an error such as "%%os%% Can't Open The NED File Extension". Customarily, this means that OMNeT++ is not installed on %%os%%. The OS won't know what to do with your NED file, so double-clicking to load the file doesn't work.

Tip: Another NED-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Outdated OMNeT++

It is possible that your version of OMNeT++ isn't able to open your OMNeT++ Network Description File file due to incompatibility. Visit the OpenSim Ltd website to download (or purchase) the latest version of OMNeT++. This problem is predominately due to having a OMNeT++ Network Description File file version that was created by a newer version of OMNeT++ than what you have installed on your PC.

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

Summary: Not having the right OMNeT++ version on your computer can cause problems opening NED files.
