Issue Details

  • I am using LabVIEW to open and read a specific format (like .mdf, .uff, .mat or others). Upon attempting a read or write operation on the file using data storage functions (DataPlugins), I get the following error dialog box:
  • Why is this error occurring? How can I read or write these files in LabVIEW ?
  • I am building an installer and I get Error -2564 when I run the installer in other computers. I don't get the error in the development computer.
  • When running an executable on a new system, my machine receives Error -2564. How do I fix this?


This error comes up when the requisite software packages (plug-ins) to support the format of the file you are trying to open are not installed through LabVIEW or DIAdem.

If you are building an installer, the DataPlugin's must be included in the application. If using Storage/DataPlugin VIs, be sure to include the NI-USI installer as well.

For example, for .mdf files, the following plug-ins need to be installed on a machine:

Additional Information

Two different data plugins may be required, as they each refer to different formats of the specific filetype (e.g. MDF).
