Any idea what is the error number is tied to? While trying to install and activate a new userid and passwd from 5 user pack. The 3rd PC installed, failed to activate with this error number. No cross ref or other text on the error message. Repeated several times before clicking to submit ticket. After clicking to review info before submitting error report, the activate license suddenly succeeded. Sync problems or am I supposed to wait between each activation Event log has one entry for invalid userid passwd, no error number. Of the several attempts this is the only error msg in the log which was also the only error that was in a balloon popup. Thinking this was a separate error from the update module and not related to the activate prompt. NOD32 5 Home new userid issued. Old install was Biz ver NOD32 4, the biz license was active and cleared from the system when uninstalled 2 days ago.
