Issue Details

I have installed a DataPlugin successfully, but when I try to use the Open Data Storage Express (VI) to open a file, the installed data type is not listed as a selectable storage format.


 1. Verify that the DataPlugin got correctly installed, we can verify this by following these two options:
  • If the NI Package Manager is installed on the computer, the DataPlugin should show up under the installed software as follows:
NI Package Manager
  • If the pc does not have NI Package Manger installed, then the DataPlugins will appear in the list of installed products after you select Uninstall/Change for National Instruments software in the windows uninstall control panel. See the photo for an example:
NI Software DataPlugins
  • You can use a LabVIEW example to verify that the component is installed. Please open the following example. Go to Help >> Find Examples... >>  Fundamentals >> File Input and Output >> DataPlugin >> Manage Open the example and run it, this will show us a list of the installed DataPlugins in your pc. Please check if the desired data format is listed as in the following picture:
DataPlugin Manager Example

2. If the DataPlugin does not show up in either of those lists please proceed with running the executable to install the DataPlugin.

3. If the DataPlugin is still not showing up in the list of supported data types it is probably due to a registration issue. Navigate to the folder where the DataPlugins get installed:
  • Newer C++ DataPlugins install to this folder: C:\Program Files (x86)\National Instruments\Shared\USI\DataPlugins\<DataPlugin Name>
  • Older C++ DataPlugins install to this folder: C:\ProgramData\National Instruments\Shared\USI\Plugins\DataPlugins\<DataPlugin Name>

4. Double-click the file there with the extension URI (and with the same name as the DataPlugin) to register it.
