I'm not really a programmer by trade. I know my way around Python and have been through some programming classes back in college. Anyhow at work I use Windows and would like to use Icecat but it's not really working out so hot. I installed Visual Studio and various other requirements per the Mozilla Windows build instructions, but it's not really matching what I'm seeing. There was a batch script included with the source so I figure why not try that, "start-shell.bat" and it exited with this error:

U:\Users\elementalpee>IF "0" == "1" (START U:\Users\elementalpee\Downloads\icecat-52.3.0-gnu1\ic
ecat-52.3.0\msys\bin\mintty -e U:\Users\elementalpee\Downloads\icecat-52.3.0-gnu1\icecat
-52.3.0\msys\bin\console U:\Users\elementalpee\Downloads\icecat-52.3.0-gnu1\icecat-52.3.
0\msys\bin\bash --login )  ELSE (U:\Users\elementalpee\Downloads\icecat-52.3.0-gnu1\icec
at-52.3.0\msys\bin\bash --login -i )
The system cannot find the path specified.

Near as I can figure, it's looking to see if I have some kind of "mintty" thing, determining that I don't, and then instead trying to run some kind of bash shell. It is true what it says when it says it can't find it. There is no such "msys" folder in the icecat-52.3.0 folder.

Any thoughts on how I ought to proceed from here? Am I barking up the wrong tree with this batch script to begin with?

Edit: Not sure if it's relevant but I'm trying from Win 7 Enterprise 64.
