I'm asking in this forum because I've sent Eset five support requests in the past week, and I've not gotten any response. Whenever I attempt to update the virus signature database, whether through an automated process or manual event, I get the following error message: Time Module Event User 6/15/2004 20:14:02 PM Update Error occured while updating program modules (Cannot replace the current file.) When I trigger the update, I see a series of files get downloaded into the ESET\updfiles subdirectory. The update then creates a file nod32.xxx in the Eset directory, and immediately afterward I get this error. I've tried disabling the AMON and IMON modules, and it makes no difference. As nearly as I can tell from enabling auditing on this directory, the error comes from trying to replace nod32krn.exe. I can find no documentation that either describes this error or a workaround. Windows XP Pro SP1, service running under the LocalSystem account, which has "Full Control" access to all the Eset files. I have purchased NOD32. The program can access and download the updates, it just cannot complete the process.
