Inventor 2020 PRO cannot start

Hello every one!


I have been using Inventor since the version 2015 and this never happened to me before. The problem is when I start the program, the loading screen appears like in the picture and when the loading bar gets to 50%, the loading screen disappears and nothing happens.

I reinstalled my WIN 10 64 bit a few days ago and installed the Inventor 2020 Pro again and everything worked fine for 3-4 days and now the same problem happens. The WIN 10 is official. I tried to repair the program, I tried updating it, I used Inventor Reset Utility, I looked into the Task Manager to see whether Inventor is working in the background, but nothing helped. I doubt that the solution is to reinstall my Inventor every couple days.


Has anyone had a similar problem? Please help if you can.

Hi! This could be licensing related. Please follow the instruction below to update the 2020 product line licensing service.


Many thanks!

Thank you for the reply. I have reinstalled WIN 10 again because I was really in a hurry. I have installed again Inventor 2020 and I followed your advice and updated the software. If the software continues to work good after few days, I will accept your solution as a sound one.
