Inventor will not open :(

[Anonymous]

I just installed inventor pro. 2016 for my windows 10 but when I tried to open it my computer loaded for a while but at the end nothing appeared. I tried again and the same thing happened. I don't know what I should do now and I only want to uninstall and reinstall as a last resort. What Should I DO!!!

Have you already checken the tips on this post. 

Inventor will not start

did it finish installing?   Also did you install all of the updates as well?

Did you try running it as Admin from the icon on your desktop?

I tried inventor the next day and instead of nothing showing up a message
popped up saying error: Inventor needs to reregister.

I'm confused at what this message means and if the message is normal.

What happens if you click OK?

Have you had more than one version of Inventor installed on this machine?
