Error installing tomcat

Hello friends, I downloaded tomcat7.0 version to my Windows Vista 32bit OS sys.
I am writing the details as to what I downloaded and what the error is. Please help me as I am stuck with this since 3 days.

I downloaded the following

apache-tomcat-[version]-windows-x86.zip
32-bit Windows specific distribution that includes the Windows service wrapper and the compiled APR/native library for use with 32-bit JVMs on both 32 and 64 bit Windows platforms.

I tried to run the startup.bat that is in the tomcat bin directory at command prompt and it says

"the JRE_HOME environment variable is not defined correctly. This environment variable is needed to run this program"

I set the Environment variable as follows

1. JRE_HOME
C:\PROGRAMFILES\JAVA\JRE6

2. JAVA_HOME

C:\PROGRAMFILES\JAVA\JDK1.6.0_30

3. CLASSPATH

C:\PROGRAMFILES\JAVA\JDK1.6.0_ 30\JRE\LIB\RT.JAR

4. PATH

C:\APP\TOMCAT6.0\APACHE- TOMCAT-7.0.25\BIN

This is what I read should be set. please see and let me know what could be the problem.
thank you

I guess PROGRAMFILES usually looks somewhat like this Program Files.

Remember, Java is case sensitive even if Windows generally isn't.

Hi all, the Tomcat is working. I read the RUNNING.TXT file that comes with download and it helped me. Also at dos prompt i run catalina.bat and it showed me all teh envi vables that it set and then I run some config debugger file I think and probably it rectified the problme. Thank you for taking time.
