This is ridiculous as I still have about 35GB left in my C: drive.

Uninstalling and re-installing live update did not work for me. Any other suggestions ?

Does Symantec have an answer for this? I seem to recall an article on the subject that talked about clearing all the prior downloaded files from Live Update and then re-installing LU but I cannot recall the location where LU places the downloaded updates..

I also have problems with the LU 1863 error.
Just installed Ghost 12 with the latest LU update.

Just tried to increase the cache space but no luck. A solution for this rare problem please!

I've got WinXp with more than 30GB left of the partion where Norton is placed but there is despite the LU 1863 error
reinstall Live Update doesn't help
do anyone of you have a solution?

i was getting this trying to update ghost console on a 2003 server with over 200GB of free space on the c: drive.

To fix this i just bypassed my proxy server and the update run without any problems.

odd that changing my internet explorer setting would fix the above, but it worked for me.

Thanks for your answer - may be it's a connection problem I'll check this, but I don't think so. I'm linked with a modem directly to the Internet so I don't know what to change.
The programm I'm using is Norton Anti Virus 7 but it could be the same problem as well.- in addition to the reinstallation - now I can't update any thing - not even the updates up to july I already downloaded.

Any suggestions? I, too, am vexed with this problem.
I cannot get live updates.
Instead, I keep geting this error message below.

I attempted to remove Live Update as suggested above but I received a warning that made me think there has to be a better solution.
I have loads of space. Just to be sure I ran defrag, purged my cookies, temp internet, etc.

It is still a no go.

Connecting to ...
Unable to connect to host
LU1863: There is not enough free disk space for LiveUpdate to operate properly. Please free up disk space on your computer and run LiveUpdate again.

I got this same error after installing Symantec System Recovery. I turns out that my content filter was blocking LiveUpdate. Odd, because it was working before.

Beware if you are using GFI Webmonitor or any internet gateway URL scanning products.

You have to bypass scanning for the following liveupdate URL

I had the same problem and it turned out to be the web filter that we run at work. LU1863 error is misleading, the problem was that our web filter was blocking access to Live update and it was unable to reach the Symantec web site.

Hi all

Happy New Year

Thought I should update my posting. After trying everything I could think of including emtying the liveupdate cache (from config applet in control panel), I could not connect to the server so I closed up for the night.

Today I started up and live update ran automatically and after what seemed quite a long time (maybe a couple of minutes) it has corrected itself and managed to download the file it was having trouble with. The log and setting files have been updated so here's hoping the problem is resolved.

Why though is another question altogether. I'm guessing from examination of the log and setting files that an incomplete download file triggered the condition. Perhaps it tried to resume the download but couldnt and so just crapped out with that error message which could well be a kind of default message (on the else leg of a case statement maybe?)

So the resolution could be to reset the settings file and delete the offending partial download. The latter could be difficult as NIS or maybe just liveupdate seems to have control of it. So perhaps the following:

turn off run all norton products at start up
start in safe mode but go to cmd prompt
navigate to downloads folder
delete partial downloaded file as determined previously through examination of setting file
(may need to change attributes first to allow delete)

Now restart in safe mode to normal windows
turn on norton start up
restart and this time liveupdate will fire (if in auto mode)
This may work if not you'll need to edit the settings file to remove the entry indicating partial download (to be honest this may prove difficult if read only and owned by norton/liveupdate - perhaps a repeat of the above turning everything off and also ensuring the services dont start also)

Well there you go - dont know if this helps. Normal health warnings apply people - this is only my idea of a possable resolution use by your own choice. ALWAYS BACK UP ANY IMPORTANT WORK FIRST.

One final thought. I dont see why uninstalling and reinstalling shouldnt work. Make sure that all the liveupdate flder structures are removed after uninstalling. I think there is also a tool available to clean out the registry too. Or you could always manually do it........(for the very brave only and do take a registry backup if you take this route)

All the best

The best fix for anything symantec is to install

I have spent an entire afternoon with symantec support to figure this out.

Sam has got it right.
Any content filter will result in this error.

"You have to bypass scanning for the following liveupdate URL
* "

The above works, My setup ...squid manual proxy ....dansguardian... got to get past dans guardian. Live update custom settings to use proxy.

I had the same problem, I also reinstalled and nothing. The problem was Internet access. I was not connected to the Internet at the moment and when I connected, the error went away. I hope this works.
