Update required before transmitting, update stuck at 'waiting for installer', restart required. Can't restart in the middle of filing.

An excellent resource for resolving these types of situations is here: E-filing Problems, which includes other support articles like What if Transmit Returns doesn't work?

Otherwise, see:

• See the Troubleshooting dropdown in this article for Microsoft's .NET Framework Repair Tool and a System File Checker: Troubleshooting problems with Windows Installer and the Microsoft .NET Framework
• Running the Windows System File Checker
• For more information, see: Error 1603: "A fatal error occurred during installation or updating".
