Issue Details

  • I just installed DIAdem and when I open DIAdem I see the splash screen for a couple of seconds and it closes without any error. I tried repairing and reinstalling the software without any success.


This issue happens when some dlls are not correctly registered in the installation process. To solve this issue, please follow the steps below.
  1. Open the command prompt(CMD) as an administrator. You can do this by searching on the windows menu "cmd" and select "Run as administrator".
  2. Run the following commands:
    • cd C:\Program Files\National Instruments\DIAdem 2020
    • where regsvr32.exe
  3. If the Response is “C:\Windows\System32\regsvr32.exe” then execute the following commands.
  • "%SYSTEMROOT%\System32\regsvr32.exe" "C:\Program Files\National Instruments\DIAdem 2020\DataFinder_GUI.dll"
  • "%SYSTEMROOT%\System32\regsvr32.exe" "C:\Program Files\National Instruments\DIAdem 2020\DataStoreElements_GUI.dll"
