Norton internet security and Utilities

I have installed the above on 3 computers.  All running a different operating system.  Vist, Windows 7 and XP.  All 3 have the same window pop up stating;

 

asoelnch.exe unable to locate component. this application has failed to start because mapir.dll was not found. 

 

Only one of the PC's has had a previous vers of Norton so that cannot be the problem.  It does not appear to affect anything it is just annoying and I would like to understand what the problem is.  I have uninstalled and installed again but still happens.  Any answers??
