[GRASS-user] Error 126 with Windows 10

[John Wall]

Hello,
I am attempting to get GRASS 7.2.1-1 installed on my Windows 10 machine
using the Osgeo4w Set-up x86 utility. I chose Advanced Install and then
Install from Internet. After installing and restarting my machine, I tried
to start GRASS, but got the following error:

WindowsError: [Error 126] The specified module could not be found

What do I need to do to get GRASS to launch?
Thanks,
John
