Technical Solution



A Symantec Endpoint Protection Manager (SEPM) server is unable to perform LiveUpdate successfully.  Sessions end in Error LU1832




"LU1832 LiveUpdate was unable to compress an update because the update was corrupted during its download. Please run LiveUpdate again to re-retrieve your updates".


The virus definitions are becoming corrupted due to a firewall, or the previously downloaded updates are corrupt.


Following the steps as below should clear out potentially corrupted contents on the SEPM:

1. Stop the Symantec Endpoint Protection Manager service by Start > Run > services.msc > Symantec Endpoint Protection Manager > Stop > OK

2. Delete only the contents of

 "C:\Documents and Settings\All Users\Application Data\Symantec\LiveUpdate\Downloads" and "C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp"

Delete the 9-digit numerically-named folders (the micro-definitions) inside each of the monikers, the long alphanumeric folders in  "\Program Files\Symantec\Symantec Endpoint Protection Manager\Inetpub\content"

3. Start the  Symantec Endpoint Protection Manager service.

4. Open the command prompt and navigate to "\Program Files\Symantec\Symantec Endpoint Protection Manager\bin" and type in the following command, "lucatalog -cleanup" and press enter

5. Type the command "lucatalog -forcedupdate" and press enter

6. Run the LiveUpdate from the Symantec Endpoint Protection Manager .


(Note:  There is another LiveUpdate issue that might occur after performing the above troubleshooting steps in some scenarios. The LiveUpdate would be successful but still would not download the virus definition updates and show a note that, "No updates found for Symantec Endpoint Protection Win64" and "No updates found for Symantec Endpoint Protection Win32", as shown in the figure below. This is because Liveupdate is not integrated with the SEPM. Please perform a repair on the SEPM with the installation disk to resolve the issue.)

If the issue is still not resolved, go through the following steps, uninstall and reinstall LiveUpdate as described in the articles referenced below.
