Hi all.

I have a problem with opening file (.ms14). I have academic version of NI Multisim 14.2.


Yesterday I worked on this project for over 10 hours and everything was fine. This is a simple digital watch design. This is my final project for studies. 



Thank you in advance for your response.

Could you please share the project? I'll try to open it on my side and see if the error occurs or not.


Best regards.

Are you trying to open the project on another PC?

Yes, I have tried to open it on a few other PC and the problem still exists. I tried also reinstal NI Multisim.
Perhaps the reason was saving the file in the Onedrive cloud and possible interruption in the internet connection while working on the project.

Take a look at the article.


This issue could be caused by one of the followed points:

  • Whether the MS14 file is damaged.
  • Whether the MS14 file is incorrectly linked in the registry entries.
  • Whether the MS14 file extension has been accidentally removed from the Windows registry.
  • Whether the installation of an application that supports the MS14 file format is incompletely.
  • Whether the MS14 file is infected.
  • Whether the drivers of the equipment used for opening a MS14 file are up to date.
  • Whether your computer has enough hardware resources to open a MS14 file.


As I am facing the same issue on my side I think that the file is damaged and the solution would be creating a new one (((

I would suggest saving it on the PC but not in cloud services to avoid such kinds of issues.


Have a nice day!
