Re: New Error NIS12

Hi Warden30,


Did this just start happening recently, as in since yesterday?


Does this happen when clicking on Support > Get Support? If so, do you see a screen like the one in the following post?


If so you can check the version of the files in the post above. If you have this update and you receive the error under these conditions, then this is a known problem which Symantec is working on. It does not affect the normal operation of NIS other than this error being incorrectly reported.


Hope this helps.


Best wishes.
