Multisim Error: “Problem accessing the database” on Startup

[arios292]

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:

1. Edited some Windows registry keys following suggestions from older NI forum posts.

2. Completely uninstalled and reinstalled Multisim.

3. 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
