Can't start spark shell or pyspark in Windows 7

cd\spark\bin dir
spark-shell
yields following error:
find: 'version': No such file or directory
else was unexpected at this time

Same error with
spark-shell2.cmd

PyShell starts but with errors and doesn't work properly once started
(e.g., can't find sc). Can send screenshot of errors on request.

Using Spark 1.3.1 for Hadoop 2.6 binary
Note: Hadoop not installed on machine.
Scala works by itself, Python works by itself
Java works fine (I use it all the time)

Based on another comment, tried Java 7 (1.7.0_79), but it made no difference (same error).
