ESET product activation issues

You may be experiencing issues when trying to activate your new or existing ESET product (error messages ECP.4098 or ACT.0).

We have implemented a fix that should resolve the issue but it may take some time to be put in place, please attempt to activate at a later time.

You may also experience issues with recently renewed licenses. Your ESET product may still show that your old license will expire soon, even though you already renewed it. We have recently deployed a fix for this issue and the renewed licenses should reactivate in your product soon. To reactivate the license immediately, follow the instructions in the Knowledgebase article: Activate my ESET Windows home product using my Username, Password, or License Key.

Thank you for your patience, we apologize for the inconvenience.
