Inability to launch Autodesk inventor software after successful download

[okechukwuogugua324]

I downloaded and installed the Autodesk inventor software on my laptop but after installation, the software could not open instead a prop up message appeared which read thus, 'Inventor cannot access licence' but it advised me to check that I have internet access and Stop/Restart the license but I don't know how I can restart the license server, pls help me.

I am guessing (because you haven't described much here) that you are using version 2020 or above, as a single-user license. See in the link above the advice for "Single-User (Stand-alone) License Type".
