I have tried everything that I can find on the website. I have signed in as Administrator, I have the Firewall/virus protection turned off, I looked for .NET Microsoft errors, I did a manual download of the update and installation seemed to go through, but when I try to open the Turbotax program, it asks for updates, and I get the same Microsoft installer error: 1603; so, I cannot open the program. I need to speak with a real customer AGENT!!
