Troubleshoot NDV Files
Common NDV Opening Problems
ENVI Disappeared
When trying to open your NDV file, you get the error "Can't Open NDV File Type". If so, it typically means that you don't have ENVI installed for %%os%%. This will prevent you from double-clicking to open the NDV file because the OS doesn’t know how to handle it.
Tip: If you know of another program that can open your NDV file, you can try opening it by selecting the application from the programs listed.
Outdated ENVI
Your ENVI N-D Visualizer State Data file is incompatible with ENVI because you might have the wrong version installed. Download the latest ENVI version from the Exelis Inc. website to ensure you have the correct one installed. The primary cause of this problem is that your ENVI N-D Visualizer State Data file was created by a different (newer) version of ENVI than what's installed.
Tip: Find clues on the correct software version by right-clicking your NDV file and clicking "Properties".
Regardless, most of the NDV file opening problems relate to not having the right version of ENVI installed.
Associated Difficulties Loading NDV Files
Assuming you have the right ENVI version installed, other problems can prevent you from opening NDV files. If you're still experiencing problems opening NDV files, there could be other computer problems. These issues include:
- Invalid NDV file references in the Windows Registry (the "phonebook" of the Windows Operating System)
- Mistaken removal of the Windows registry NDV description
- Partial installation of ENVI that did not fully complete
- File corruption affecting your NDV file
- The NDV is infected with a virus
- Device drivers of the hardware associated with your NDV file are corrupt or out-of-date
- Windows cannot load your ENVI N-D Visualizer State Data file due to insufficient resources (eg. RAM)
