Creo 3 won't install, Pending Prerequisite

Hello,

I downloaded Creo 3 student version and am trying to install it.  Following the instructions everything goes well, license looks like it installs and I get the "Success" message.  Click next and Install.  Several of the items look to install, but several are stuck with status "Pending Prerequisite".  Can't click back or any of the other buttons. 

Firewalls are disabled. 

I did search the forums and found this post:Re: Can't download Creo 3.0: 'Pending Prerequisite', checked my task manager and found no msi.exe.  Did not find any other hits.

Any help would be greatly appreciated.

Thanks

Greg
