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"

Additional Information

If this doesn't work, it is likely that the error is related to End Point Protection being used. During the installation, it is necessary to have access with admin privileges to the registry. During the DIAdem session, the registry must be open for normal uses access. In addition, all DIAdem relevant files and directories must be set on a “whitelist” of the End Point Protection software.
