Install Manager wont install

I had Creo 4.0 student edition previously installed on my laptop for school. It was working fine all semester until one day I got an error message that my license was invalid or something along the lines of that. I had then uninstalled Creo completely from my computer and tried to redownload it. However, when I use the install wizard it only installs the shortcuts and none of the software, in fact even inside the install wizard it shows creo parametric and the other programs I had downloaded as 0gb for the file size which I thought was odd as well. If anyone can figure out what is wrong with my install wizard I would greatly appreciate it!
