How to configure project under AndroidStudio sdk1.3, ndk on Win8.1 to build correctly? - ndk-build

Question

ndk-build ends with error for any project I try to run.
I am using androidSDK 1.3 with ndk-bundle on windows 8.1
second empty .c file added to jni folder;
local.properties shows sdk and ndk path corrects:
ndk.dir=C\:\\Users\\JL\\AppData\\Local\\Android\\sdk\\ndk-bundle
sdk.dir=C\:\\Users\\JL\\AppData\\Local\\Android\\sdk
error message:
* What went wrong:
Execution failed for task ':app:ndkBuild'.
> A
problem occurred starting process 'command 'ndk-build.cmd''
