[SOLVED] Rapidminer\scripts not working in 5.3?

Am I the only one seeing errors with the scripts in 5.3?  If I try to execute any of the files in the scripts directory on 5.3, I get the error:

RAPIDMINER_HOME is not set. Trying the directory 'C:\Program Files\Rapid-I\Rapid Miner5\scripts\..'...
Using local jre: C:\Program Files\Rapid-I\RapidMiner5\scripts\..\jre\bin\java.exe...
Starting RapidMiner from 'C:\Program Files\Rapid-I\RapidMiner5\scripts\..' using classes from 'C:\Program Files\Rapid-I\RapidMiner5\scripts\..\lib\rapidminer.jar'...
Creating file "\\check_rm_java_version"
The filename, directory name, or volume label syntax is incorrect.

The problem seems to be the line in the .bat files that says:

set CHECK_VERSION_FILE="%HOMEPATH%\check_rm_java_version"

At least on my machine, HOMEPATH=\, so this ends up putting doubled slashes in the file create, which fails.  Correcting that problem leads to this:

Usage: com.rapidminer.RapidMinerCommandLine [-f] PROCESS [-Mname=value]
  PROCESS       a repository location containing a process
  -f            interpret PROCESS as a file rather than a repository location (deprecated)
  -Mname=value  sets the macro 'name' with the value 'value'

It appears that the new build of CommandLine insists on getting a PROCESS passed in.   Without thoroughly testing it, it does appear that the script will work if you pass in a valid process path.
