Troubleshooting Problems Opening NDL Files

Issues Opening NDL Files

IBM Lotus Notes Disappeared

If you attempt to load your NDL file, you experience a message such as "Can't Open NDL Files". Generally, this is experienced in %%os%% because IBM Lotus Notes isn't installed on your PC. Your operating system cannot associate your NDL with IBM Lotus Notes, so double-clicking the file won't work.

Tip: If you have another software that you know opens NDL files, you can select it by hitting the "Show Apps" button.

Outdated IBM Lotus Notes

In other instances, your Lotus Notes Doclink File file version may not be supported by your version of IBM Lotus Notes. Visit the IBM website to download (or purchase) the latest version of IBM Lotus Notes. Your Lotus Notes Doclink File file was probably created by a newer release of IBM Lotus Notes than what's currently installed your computer.

Tip: Investigate your NDL file by right-clicking and selecting "Properties" to find clues on what version you need.

Conclusion: The majority of NDL file opening issues are due to not having the correct IBM Lotus Notes version installed.
