Cannot install programs now that Norton Security Suite 4.0.0.127 is installed.

I'm trying to install palmone software.   I'm getting the following message:  setup was unable to access the Internet.  Check your internet connection and verify that it is working properly.   I can access this forum, so the internet is working fine.  So, firewall needs to be turned off.  I turn off the smart firewall.   I still get the same error message.   

 

On a related front, I have an HP printer with wireless access.  When I try to install the printer drivers for it, I cannot see the printer.  This appears to be a firewall related issue.  I spent several hours allowing around 20 or so HP program to be added to the firewall, but none of them seem to work.  So, why can't I access printers through the network.  It works on another computer (that doesn't have Norton Security Suite installed).

 

Hmmm,
