You don't need to set your PATH if you use batchfiles. Their
purpose is avoid having to do that in the first place. That
may not be related to your main problem though.

Here are two things to try:
1. Just a guess but you may need to run this elevated. Using
el.js from the batchfiles:
el cmd
and allow it to proceed when asked. That
will spawn a new window from which everything will run in
elevated mode. Try your Rscript command in that.
2. Another thing to try is running without using the batchfiles.
Go into R and enter this:
file.path(R.home(), "bin", "Rscript.exe")
and it will give you the path to Rscript.exe. Using that path
try this:
"...whatever.../Rscript.exe" -e ...your command...
