command to run command prompt

2016 won't install on laptop (see other thread)

upgraded other PC from W8.1 toW10. Start button

does not work. tried all suggestions produced by Google

except REFRESH.

2016 does install

tried ifort directly after executing psxevars.bat-- linker error.

Is there a way to start an IVF command prompt window from

a command prompt window (or clicking on some file, or

whatever)?  Thanks.
