Turbo tax will not update - keep getting error code - worked fine for the last two weeks now stuck - seems to b connected to "Intuit Update Service 4"

You may need to contact customer service directly for assistance. Please see the following information here for more details.

Reboot your Windows OS again, just in case that helps....could be a partially=-installed update that isn't quite done yet.

Other thing to try:

Download and install the manual update for TTX:

Manually Update TurboTax for Windows Software (intuit.com)

This only does the main Federal part, so you might need to run an in-software update again after it is done, for yoru state forms.
