I'm using window vista 32 on my laptop and my smart update does not work on this computer. Everything else works fine. Norton Utilites and the smart update works fine on my desktop win XP as well. I get the message on my laptop that upate.exe does not have a program associate with it and to go to the Set Association control panel (SACP) and set an association. In the SACP, there is no file extension for update.exe or anything else to do with Norton. My question, what is the file ext. for smart update that I should be looking for? What to do?? Thanks.
