Hi Bill,
In order to add some info with this conflict between Win Update & Win Def,
for my computer, all updates are done by MS update and Win Defender is
unable to do anything (such as verifing that no update is needed). The
message is a mix of english & french (my XP home is a french version).
English part is "Windows Defender was unable to complete the update:
0x8007064c." French part could be roughly translated by " Install source for
this product is'nt available. Verify source is existing and you can access
it".
Hope this can help.

|| ||| Puzzled. Windows update, when i ran it, said there was an update
||| for Defender. I downloaded it. I got an error notice that said it
||| did NOT install. When I look at the definition version, engine and
||| version, they all
||| are the most current - i.e. those listed on this site as of 7/18
||| (def.
||| 1.14.1530.8; version 1.1.1347.0; engine version 1.1.1508.0). So it
||| appears
||| that despite the error message, it did update.
|||
||| And..... in spite of having it listed in services, and permitted
||| under the firewall settings (xp), and trying to turn it off, then
||| on, or change times,
||| it will STILL still not run automatically.
