ThinkVantage Toolbox cptasks.xml Installation Error

I want to install the latest version of the Lenovo ThingVantage Toolbox but I am having some trouble installing it. When I attempted to install it, it would stop on the file "cptasks.xml". After that I run the ThinkVantage toolbox but I a message from Windows pops up saying that the application was unable to start correctly. I am suspecting this could be due to the installation I did earlier which failed. How shall I resolve this problem? Please someone help me. Thanks.
