NV3 Troubleshooting
Typical NV3 Opening Challenges
Unknown Software is Not Installed
When you double-click your NV3 file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". If this is the case, it's usually due to the fact that you do not have Unknown Software for %%os%% installed on your computer. You won't be able to double-click to open your NV3 because your OS doesn't know what to do with it.
Tip: Another NV3-related program can be selected to open the file by clicking "Show Apps" and finding the application.
Incorrect Unknown Software Version
It is possible that your version of Unknown Software isn't able to open your Visicontrol MVS-30/35/40 Flash-memory Backup file due to incompatibility. If you do not have the proper version Unknown Software (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. 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 NV3 file, selecting "Properties", and looking at the version information.
Conclusion: The majority of NV3 file opening issues are due to not having the correct Unknown Software version installed.
More Causes of Problems Opening NV3s
Even with the correct version of Unknown Software installed, you can still experience difficulties opening NV3s. If you are continuing to have errors with loading NV3 files, other external issues might be to blame. Problems unrelated to software:

- Corruption of the NV3 file description inside the Registry
- Incomplete or bad installation of a software application associated with the NV3 format
- Your NV3 file is corrupted (issues with your Visicontrol MVS-30/35/40 Flash-memory Backup file itself)
- Your NV3 is infected with malware
- NV3-related hardware has device drivers that obsolete
- Windows has inadequate resources to open your Visicontrol MVS-30/35/40 Flash-memory Backup file
