Hi everyone,
I’m having an issue with NI Multisim. When I try to launch the program, I immediately get the following error message:
“Problem accessing the database”
The application won’t start after that.
Here’s what I’ve tried so far without success:
Edited some Windows registry keys following suggestions from older NI forum posts.
Completely uninstalled and reinstalled Multisim.
Restarted the computer after each attempt.
Details about my setup:
Multisim version: Multisim 14.3
Operating System: Windows
Has anyone encountered this issue recently or found a reliable fix?
Any help or guidance would be greatly appreciated.
Thanks in advance!

Hello arios292, There are several ways to resolve this issue, try this in this order first:
• Look for the newest update/version of Multisim here: Télécharger Multisim - NI
• Uninstall, repair then reinstall Multisim in some cases it worked.
• You can follow the steps of the next link: Problem Accessing the Database When Launching Multisim - NI (BUT take care it will use windows registries and it might affect your computer)
Have a good day,
Hugo
