I took a gamble on google with
https://www.google.com/search?q=ERROR+MSg+says%3A+%22this+app+can%27t+run+on+your+PC%22+.&ie=utf-8&oe=utf-8 and first hit details a lot of work.
More than I'll copy here.
Hello & Thanks ,
I have downloaded and installed C:\FFMPEG
Can't run it with ffmpeg-01.bat
ERROR MSg says: "this app can't run on your PC" .
It runs fine if I enter it at CMD Prompt .
PLs, How can I get it to run with a *.bat ?
