<cmd_output OS="XPsp2">
E:\>set /a c = 0x1A90
E:\>net helpmsg %c%

The system cannot find message text for message number 0x1a90 in the message file for NETMSG.

See if your OS gives a different response to a net helpmsg 6800

Is it this?:

(Live Search for
6800 codes

6800 The function attempted to use a name that is reserved for use by another transaction.

As usual it doesn't seem very informative using just the code to try to
deduce what is wrong. Try searching all files which were changed by the
update for any instances of the code (in both its decimal and hexadecimal
representations.) Assuming you find log files that way (or other diagnostics)
see if the context(s) that you find the code in give you any more clues.

Hmm... note that another poster mentioned this code in an earlier thread
about what seems to be a related code: 80071AA7

E.g. that one seems even more cryptic: <eg>

"The file cannot be opened transactionally, because its identity
depends on the outcome of an unresolved transaction."

Good luck

"I am answering late because this is still a problem for many people.

Solution: My wife had this same problem with 27 updates that failed with error code 80071A90 . It turns out that it is all about your internet connection. It has to be an Ethernet connection and not a WIFI connection. This is because WIFI in many situations does a reset during the download and that causes errors during the update download. Temporarily changing to an Ethernet connection solved the problem along with only doing a few (sometimes just one) updates at a time and not all 27 updates at once."
