inventor 2020 won't launch, close itself before running

[Anonymous]

I just installed the last inventor after days of unistall the 2018 version and all autodesk products before 2020 and cleaning the temp files over and over. Now, after finally install it, the program is not running, get stuck and close itself. I'm not sure if there is some kind of license problem (student license) because its not appering on my downloaded programs at my autodesk account, it just apperars the autocad 2020 i recently intalled which its also not working either.....What should i do?....help please

Press Win+R
Digit msconfig and Enter
On the tab Services, check if Autodesk Desktop Licensing Service is running (there is the FlexNet Licensing, but it was used just until 2019).

There are two flexnet services but no Autodesk desktop license service on list, just Autodesk desktop app service and autodesk simulation moldflow mitsi 2020 jopb manager.

Have you requested a new 2020 license for IV - you need to do this each version

If not, have you updated the licensing mechanism, if not follow this:
