If you are having subscription problems it is necessary to obtain Symantec program updates and the file Lrsetup.exe. Because simply replacing the file Lrsetup.exe alone will usually not fix subscription problems, please read the document, How to fix subscription problems.
If you are not having subscription problems, start NAV and then run LiveUpdate.

NOTE: If when you click OK in step 4, you see the message "Load Library Failed," follow these steps:
Close all of the programs that are running in the background. For instructions on how to do this, see the document How to close open programs.
Click Start, and then click Run. The Run dialog box appears.
