Can't See DataPlugin in DIAdem After Successful Installation

Issue Details

I have installed a C++ DataPlugin successfully. But when I try to use Open with… in NAVIGATOR to import a file with the installed DataPlugin, I don’t see it in the list of selectable DataPlugins. Also, if I go to the menu Settings >> Extensions >> DataPlugins, it is not listed there.


If the DataPlugin installation was successful (without an error message), this means that the C++ DataPlugin was correctly installed and would work fine in general. In fact, only the DataPlugin registration failed.  This can happen in rare cases where you are using both an older C++ DataPlugin and DIAdem 2019 or later.  This registration issue does not occur with DIAdem versions prior to DIAdem 2019.  Any C++ DataPlugins that get rebuilt after DIAdem 2019 will no longer exhibit this registration issue.

To solve this problem:
  1. Navigate to the folder where the DataPlugin installs: 
  • 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>
  1. Double-click the file there with the extension URI (and with the same name as the DataPlugin) to register it.
