Issue Details

When trying to establish a connection between LabVIEW and DIAdem, I am getting the following error:

Error code: 2147312566 

Error loading type library/DLL in Diadem Open ->Diadem Open> 

How can I resolve this error to communicate with DIAdem using LabVIEW?


  1. This error is commonly caused by the bitness of LabVIEW and the bitness of DIAdem mismatching. If you are using LabVIEW 32 bit, make sure you are using DIAdem 32 bit. The same goes for the 64 bit version of the software. 
  2. Try unregistering and reregistering the software by following the instructions in Receiving "Error loading type library/DLL" When Using ActiveX Automation with Microsoft Excel and LabWindows™/CVI™
  3. There could have been a corruption in the installation of your software. Try force reinstalling the software by following Force Reinstall Non-Working or Corrupt NI Software.

Additional Information

Note: DIAdem 2018 only comes in 64 bit.
