Trouble Installing Word Perfect Suite 8

On every install try of WP Suite 8, I get a message that Windows Messaging needs updating, then the setup is aborted with the message that there is insufficient disk space. I am using a Dell Dimension XPS T500/256mb RAM, 20gb HD (with 9.3 gb free disk space). I was able to successfully install the same program on my laptop with only 2.3gb free disk space. What can I do?
