Re: NVDA won't install on win10
If this machine is still on 1803, that's long out of support now. The first order of business is Doing a Windows 10 Repair Install or Feature Update Using the Windows 10 ISO file, to get yourself on 1909.
What information is given to you when you hit the Windows Key, immediately type winver, then hit enter? That would be the starting point for determining edition of Windows 10 involved.

Science has become just another voice in the room; it has lost its platform. Now, you simply declare your own truth.
