Problems Installing Selenium Grid

One of the main and basic things to pay attention to installing ANT is to make sure that “Environment Variables” are set up correctly. You basically need to make sure that JAVA_HOME, ANT_HOME and Path have proper values on Windows machine in System Variables section
That’s what I have on my machine:
JAVA_HOME has value” C:\Program Files\Java\jdk1.6.0_14”
ANT_HOME has value “C:\path\to\folder\apache-ant-1.8.1-bin\apache-ant-1.8.1”
Path has value “C:\path\to\folder\apache-ant-1.8.1-bin\apache-ant-1.8.1\bin” in addition to what was there before (don't forget the semicolon).
