Installation problems

[dum]

Hi, I am new to activiti, and have a problem with the installation.
I downloaded activiti-5.4. on my windows seven machine
When I first tried ant.demo.start I git an error with the tomcat installation

I the tried again, first downloading tomcat apache-tomcat-6.0.32-windows-x86.zip .
When the unsuccessfull instalation is terminated, i have my own dowloaded file apache-tomcat-6.0.32-windows-x86.zip, but also an apache-tomcat-6.0.32.zip file in my donwloads folder.
The apache-tomcat-6.0.32.zip file is not expandable.

Here are the log when it came to the installation of tomcat
tomcat.install:

internal.tomcat.download:
      [get] Getting: http://activiti.org/downloads/apache-tomcat-6.0.32.zip
      [get] To: c:\downloads\apache-tomcat-6.0.32.zip

internal.tomcat.unzip:
    [unzip] Expanding: c:\downloads\apache-tomcat-6.0.32.zip into c:\activiti\ap
ps

Seems like something is wrong with the tomcat zip (corrupted while downloading eg.). Can you delete the apache-tomcat-6.0.32.zip file, and running the setup agian?
