If you experience problems with the activation of your Nero TuneItUp PRO software, please try the following steps:

- During the activation, please deactivate your firewall and/or security programs. In most cases, the activation server is unavailable due to connection restrictions caused by a security program or VPN connection

- If this does not work, please reset the settings of your Internet Explorer ((https://support.microsoft.com/de-de/help/17441/windows-internet-explorer-change-reset-settings)

- Please make sure that the system clock is set so that the time is retrieved automatically from the internet

- If this does not work, you should check the "TLS protocols" in the settings of your Internet Explorer. They must be activated. Here is an example using another program.
