Issue Details

I have recently installed DIAdem 2020. When I launch DIAdem, I can see the splash screen for a short time, then the splash screen disappears, and DIAdem does not start. The DIAdem log file only shows that DIAdem is started, and the example data set is loaded - nothing else.


In rare cases it can happen, that two components of DIAdem are not registered correctly. The following DIAdem version can be affected: 2019, 2019 SP1, 2020, and 2020 SP1.

To verify if your DIAdem installation is concerned, please run the following commands.

Open a command box with admin privileges:
  • Enter “CMD ” in the Windows start prompt.
  • Click right at the listed app “Command prompt” and
  • Select “Run as administrator”.

Enter these commands (for DIAdem 2019, please replace 2020 with 2019):
  • cd C:\Program Files\National Instruments\DIAdem 2020
  • where regsvr32.exe

The result should be: “C:\Windows\System32\regsvr32.exe”

If this is not the case, please enter these commands (for DIAdem 2019, please replace 2020 with 2019):
  • "%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"

Now, the DIAdem start should work fine.
