Please make sure that you don't have any security/anti-malware software on your computer that's blocking TurboTax. You also might want to try restarting the program as an administrator. To do this, right click on the TurboTax icon and select "Run as Administrator".

If you are still not able to resolve this issue, please contact our phone support team for more assistance. 

Thanks for the quick fix, however I have disabled firewall rules and stop Antivirus software. I still run into same problem. The funny thing is before upgrading, it worked.

Please contact our phone support team as they will be able to assist you further.
