Troubleshooting Problems Opening NRU Files
Common NRU Opening Problems
Nero 2018 is Not Installed
You attempt to load your NRU file and get an error such as "%%os%% Can't Open The NRU File Extension". Generally, this is experienced in %%os%% because Nero 2018 isn't installed on your PC. You won't be able to double-click to open your NRU because your OS doesn't know what to do with it.
Tip: If you don't have Nero 2018 installed, and you know of another program to open your NRU file, you can try opening it by selecting from the programs listed under "Show Apps".
Wrong Version of Nero 2018 is Installed
It is possible that your version of Nero 2018 isn't able to open your Nero UDF CD-ROM Compilation file due to incompatibility. Visit the Nero AG website to download (or purchase) the latest version of Nero 2018. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.
Tip: You can sometimes get hints about the right program version by right-clicking on the NRU file, selecting "Properties", and looking at the version information.
Conclusion: The majority of NRU file opening issues are due to not having the correct Nero 2018 version installed.
