Upgrade of your ESET application has failed

We could not upgrade your legacy application version to the latest possible version. Therefore, you are using a application version that has reached End of Life status and will be disconnected from ESET servers.

 

What should I do?

Step one

Check the current installation status of your ESET application

Do you have an account with Administrator privileges?
You need an account with Administrator privileges. If you are not an Administrator, you cannot upgrade or uninstall. Contact your system administrator to upgrade.

Is the ESET application working properly after a failed upgrade?
After the failed upgrade, open the main program window to verify the ESET application is working correctly.
If the upgrade failed and the ESET application is not accessible, or the ESET application reports a warning Security alert with multiple messages, proceed to step 2 as soon as possible.

Important

If you need help and would like to contact ESET Technical Support:

•The upgrade failed with a {GET_ERROR} error code.

•You have {GET_PRODUCT} {GET_VERSION} running on {GET_OSNAME} {GET_BITNESS}.

Step three

Install the latest version manually
