LabVIEW Error -2564 When Working with Different File Formats

Updated Jun 11, 2019

Reported In


  • LabVIEW 2017 Full
  • DIAdem 2017 Base

Issue Details

  • I am using LabVIEW to open and read a specific format (like .mdf, .uff or others). Upon attempting a read operation on the file using data storage functions, I get the following error dialog box:
Why is this error occurring ? How can I read this 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.


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.
For example, for .mdf files, the following plug ins need to be installed on a machine : The two different plugins refer to the different formats of MDF files. The one matching the format of the MDF file under question can be installed.

Additional Information

If you are building an installer, the executables of the plug-ins must be included in the application. For example, if you are using UFF files, include the DataPlugin for UFF files as explained here: How Do I Make My LabVIEW-Built Installer Run an Executable After Installation?
