Error Message - Microsoft unable to update Turbotax

[domerdoc]

May have been reported previously, but I didn't see an answer.  Have received this error last couple days.  Turbotax still seems to function OK, but I'm not sure what I'm missing with the update.  Sent error report to Microsoft.  Never had this problem before and never had to disable anit-virus with prior updates

Microsoft Installer Error 1603

Symptom: When installing a software update, the following error occurs:

"A fatal error occurred during installation."

Possible Causes

Previously was able to "restart" Turbotax - unable to do so now.  Fortunatly, I've already filed.  I'd be pissed otherwise.
