There are other things that need attention:

Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.

1. Shockwave Flash 10.1 r85
2. Next Generation Java Plug-in 1.6.0_19 for Mozilla browsers

Update the Flash plugin to the latest version.

• http://www.adobe.com/software/flash/about/

Update the Java plugin to the latest version.

• http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform: Download JRE)

Downloaded all the suggested updates. Unfortunately, still get same error message - "can't connect - error 42002. "

Did you read the TurboTax Intuit support page that I hyperlinked?

The information that cor-el posted has nothing to do with the problem you are having with TurboTax.

lbennett2 I've been having the same problem. Just found a solution someone posted elsewhere that worked for me: go to Control Panel on your PC; click Internet Options; click Connections; click LAN settings; uncheck "use a proxy server for your LAN"

I just did this and am now receiving my update from Turbo Tax. I am not a techie so I have no idea what it means, but it did work! Good luck!
